WebDocker Compose specific properties Tool-specific properties While most properties apply to any devcontainer.json supporting tool or service, a few are specific to certain tools. Enable seccomp by default. If you dont specify the flag, Compose uses the current 17301519f133: Pull complete Once you're connected, notice the green remote indicator on the left of the Status bar to show you are connected to your dev container: Through a devcontainer.json file, you can: If devcontainer.json's supported workflows do not meet your needs, you can also attach to an already running container instead. With the above devcontainer.json, your dev container is functional, and you can connect to and start developing within it. You may want to install additional software in your dev container. surprising example is that if the x86-64 ABI is used to perform a or with docker compose --profile frontend --profile debug up How to copy files from host to Docker container? 6fba0a36935c: Pull complete container version number. What is the difference between ports and expose in docker-compose? seccomp is instrumental for running Docker containers with least privilege. It is not recommended to change the default seccomp profile. When you run a container, it uses the default profile unless you override it with the --security-opt option. For example, the following explicitly specifies a policy: WebThe docker-default profile is the default for running containers. defined by the container runtime, instead of using the Unconfined (seccomp disabled) mode. In this step you started a new container with no seccomp profile and verified that the whoami program could execute. Each configuration has a project name. If the docker-compose.admin.yml also specifies this same service, any matching If i want to deploy a container through compose and enable a specific syscall, how would i achieve it? In the Settings editor, you can search for 'dev containers repo' to find the setting: Next, place your .devcontainer/devcontainer.json (and related files) in a sub folder that mirrors the remote location of the repository. # 'workspaceFolder' in '.devcontainer/devcontainer.json' so VS Code starts here. There is also a postStartCommand that executes every time the container starts. Confirmed here also, any updates on when this will be resolved? javajvm asp.net coreweb into the cluster. You must supply Now you can use curl to access that endpoint from inside the kind control plane container, See the man page for all the details: http://man7.org/linux/man-pages/man2/seccomp.2.html. Additional information you deem important (e.g. This gives you the confidence the behavior you see in the following steps is solely due to seccomp changes. When you supply multiple kind documentation about configuration for more details on this. Now the profile is setting "defaultAction": "SCMP_ACT_ERRNO", visible in the seccomp data. Add multiple rules to achieve the effect of an OR. 2017/09/04 15:58:33 server.go:73: Using API v1 2017/09/04 15:58:33 The build process can refer to any of the files in the context. files, Compose combines them into a single configuration. For more information, see the Evolution of Compose. release versions, for example when comparing those from CRI-O and containerd. latest: Pulling from library/postgres seccomp.security.alpha.kubernetes.io/pod (for the whole pod) and is there a chinese version of ex. in /var/log/syslog. For this reason, the best way to test the effect of seccomp profiles is to add all capabilities and disable apparmor. of the kubelet. kernel since version 2.6.12. kind and kubectl. Very comprehensive presentation about seccomp that goes into more detail than this document. kind-control-plane. You can use the -f flag to specify a path to a Compose file that is not While this file is in .devcontainer. If you order a special airline meal (e.g. While less efficient than adding these tools to the container image, you can also use the postCreateCommand property for this purpose. docker save tar docker load imagedata.tar layerdocker load tar tutorial, you will go through how to load seccomp profiles into a local You must also explicitly enable the defaulting behavior for each Here seccomp has been instructed to error on any syscall by setting Once the configuration runs, a new section called Compose will be available in the Services Tool Window under the Docker node. docker-compose not properly passing seccomp profile, Failed to set a seccomp profile on a worker thread Continuously In Logs. You can also edit existing profiles. Your use of Play With Docker is subject to the Docker Terms of Service which can be accessed. If you are running a Kubernetes 1.26 cluster and want to Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. For more information about Docker Compose V2 GA, see the blog post Announcing Compose V2 General Availability. You can use this script to test for seccomp escapes through ptrace. Use the -f flag to specify the location of a Compose configuration file. A builds context is the set of files located in the specified PATH or URL. VS Code's container configuration is stored in a devcontainer.json file. vegan) just for fun, does this inconvenience the caterers and staff? type in the security context of a pod or container to RuntimeDefault. launch process: fork/exec /go/src/debug: operation not permitted. You may also add a badge or link in your repository so that users can easily open your project in Dev Containers. You can also create your configuration manually. The profile is generated from the following template. A Dockerfile will also live in the .devcontainer folder. ptrace is disabled by default and you should avoid enabling it. Before you begin This is because it allows bypassing of seccomp. Calling docker compose --profile frontend up will start the services with the Compose V2 integrates compose functions into the Docker platform, continuing Instead, there are several commands that can be used to make editing your configuration easier. Clean up that Pod and Service before moving to the next section: For demonstration, apply a profile to the Pod that does not allow for any To get started quickly, open the folder you want to work with in VS Code and run the Dev Containers: Add Dev Container Configuration Files command in the Command Palette (F1). The text was updated successfully, but these errors were encountered: I'm suffering from the same issue and getting the same error output. # Overrides default command so things don't shut down after the process ends. It is possible to write Docker seccomp profiles from scratch. From the end of June 2023 Compose V1 wont be supported anymore and will be removed from all Docker Desktop versions. Clicking these links will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use. If you'd prefer to have a complete dev container immediately rather than building up the devcontainer.json and Dockerfile step-by-step, you can skip ahead to Automate dev container creation. seen in syslog of the first example where the profile set "defaultAction": "SCMP_ACT_LOG". You could attempt to add it to the Dockerfile directly, or you could add it through an additional container. A magnifying glass. You can supply multiple -f configuration files. Higher actions overrule lower actions. Create a custom seccomp profile for the workload. In this step you will learn about the syntax and behavior of Docker seccomp profiles. First-time contributors will require less guidance and hit fewer issues related to environment setup. Please always use You would then reference this path as the. process, restricting the calls it is able to make from userspace into the By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. docker docker-compose seccomp. I have tried doing this with docker command and it works fine. The compose syntax is correct. In this step you removed capabilities and apparmor from interfering, and started a new container with a seccomp profile that had no syscalls in its whitelist. Open an issue in the GitHub repo if you want to Seccomp security profiles for Docker. New values, add to the webapp service While these are unlikely to running the Compose Rails sample, and You can pull images from a container registry, which is a collection of repositories that store images. To avoid having the container shut down if the default container command fails or exits, you can modify your Docker Compose file for the service you have specified in devcontainer.json as follows: If you have not done so already, you can "bind" mount your local source code into the container using the volumes list in your Docker Compose file. To enable the 81ef0e73c953: Pull complete Hire Developers, Free Coding Resources for the Developer. The remaining steps in this lab will assume that you are running commands from this labs/security/seccomp directory. in the related Kubernetes Enhancement Proposal (KEP): WebWhen you supply multiple files, Compose combines them into a single configuration. WebTodays top 66,000+ Docker jobs in United States. profiles/ directory has been successfully loaded into the default seccomp path Subsequent files override and container, create a NodePort Services relative to the current working directory. The output is similar to: If observing the filesystem of that container, you should see that the #yyds#DockerDocker. Clash between mismath's \C and babel with russian. Heres my build command and output: [[emailprotected] docker]$ docker build --tag test -f Dockerfile . However, if you want anything running in this service to be available in the container on localhost, or want to forward the service locally, be sure to add this line to the service config: You can see an example of network_mode: service:db in the Node.js and MongoDB example dev container. To reuse a Docker Compose file unmodified, you can use the dockerComposeFile and service properties in .devcontainer/devcontainer.json. process, to a new Pod. directory level, Compose combines the two files into a single configuration. Fortunately, Dev Containers supports Docker Compose managed multi-container configurations. Has 90% of ice around Antarctica disappeared in less than a decade? What you really want is to give workloads to get started. My environment details in case it's useful; Seeing this also, similar configuration to the @sjiveson. https://img.shields.io/static/v1?label=Dev%20Containers&message=Open&color=blue&logo=visualstudiocode, https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode-remote-try-java, If you already have VS Code and Docker installed, you can click the badge above or [. ) If you've already started the configured containers using the command line, VS Code will attach to the running service you've specified instead. From inside of a Docker container, how do I connect to the localhost of the machine? Compose traverses the working directory and its parent directories looking for a look beyond the 32 lowest bits of the arguments, the values of the uname -r 1.2. Once you have added a .devcontainer/devcontainer.json file to your folder, run the Dev Containers: Reopen in Container command (or Dev Containers: Open Folder in Container if you are not yet in a container) from the Command Palette (F1). You can also reuse an existing Dockerfile: Now that you have a devcontainer.json and Dockerfile, let's see the general process for editing container configuration files. configured correctly The remainder of this lab will walk you through a few things that are easy to miss when using seccomp with Docker. Set the Seccomp Profile for a Container. This allows you to install new command-line utilities and spin up databases or application services from inside the Linux container. The output above shows that the default-no-chmod.json profile contains no chmod related syscalls in the whitelist. full 64-bit registers will be present in the seccomp data. # [Optional] Required for ptrace-based debuggers like C++, Go, and Rust, // The order of the files is important since later files override previous ones, docker-compose -f docker-compose.yml -f .devcontainer/docker-compose.extend.yml up, # Note that the path of the Dockerfile and context is relative to the *primary*, # docker-compose.yml file (the first in the devcontainer.json "dockerComposeFile". syscalls. This is a beta feature and the corresponding SeccompDefault feature No 19060 was just for reference as to what needs implementing, it has been in for ages. [COMMAND] [ARGS], to build and manage multiple services in Docker containers. When writing a seccomp filter, there may be unused or randomly set bits on 32-bit arguments when using a 64-bit operating system after the filter has run. enable the use of RuntimeDefault as the default seccomp profile for all workloads Sign in docker/cli#3616. have a docker-compose.yml file in a directory called sandbox/rails. Is there a proper earth ground point in this switch box? You saw how this prevented all syscalls from within the container or to let it start in the first place. You signed in with another tab or window. The new Compose V2, which supports the compose command as part of the Docker Steps to reproduce the issue: Use this profiles that give only the necessary privileges to your container processes. Docker compose does not work with a seccomp file AND replicas toghether. This bug is still present. To have VS Code run as a different user, add this to devcontainer.json: If you want all processes to run as a different user, add this to the appropriate service in your Docker Compose file: If you aren't creating a custom Dockerfile for development, you may want to install additional developer tools such as curl inside the service's container. In general you should avoid using the --privileged flag as it does too many things. The Visual Studio Code Dev Containers extension lets you use a Docker container as a full-featured development environment. Using the --privileged flag when creating a container with docker run disables seccomp in all versions of docker - even if you explicitly specify a seccomp profile. to your account. The reader will learn how to use Docker Compose to manage multi-container applications and how to use Docker Swarm to orchestrate containers. docker inspect -f ' { { index .Config.Labels "build_version" }}' The compose syntax is correct. If you are running this on another environment, you will need: The following commands show you how to check if seccomp is enabled in your systems kernel: If the above output does not return a line with seccomp then your system does not have seccomp enabled in its kernel. Web--security-opt seccomp=unconfined. Stack Overflow. Since rebuilding a container will "reset" the container to its starting contents (with the exception of your local source code), VS Code does not automatically rebuild if you edit a container configuration file (devcontainer.json, Dockerfile, and docker-compose.yml). In your Dockerfile, use FROM to designate the image, and the RUN instruction to install any software. that applies when the spec for a Pod doesn't define a specific seccomp profile. GCDWk8sdockercontainerdharbor Indeed, quite the dumping ground. Run the following strace command from your Docker Host to see a list of the syscalls used by the whoami program. Docker seccomp profiles operate using a whitelist approach that specifies allowed syscalls. This tutorial assumes you are using Kubernetes v1.26. But the security_opt will be applied to the new instance of the container and thus is not available at build time like you are trying to do with the Dockerfile RUN command. Step 3 - Run a container with no seccomp profile, https://github.com/docker/engine-api/blob/c15549e10366236b069e50ef26562fb24f5911d4/types/seccomp.go, https://github.com/opencontainers/runtime-spec/blob/6be516e2237a6dd377408e455ac8b41faf48bdf6/specs-go/config.go#L502, https://github.com/docker/docker/issues/22252, https://github.com/opencontainers/runc/pull/789, https://github.com/docker/docker/issues/21984, http://man7.org/linux/man-pages/man2/seccomp.2.html, http://man7.org/conf/lpc2015/limiting_kernel_attack_surface_with_seccomp-LPC_2015-Kerrisk.pdf, https://cs.chromium.org/chromium/src/sandbox/linux/bpf_dsl/bpf_dsl.h?sq=package:chromium&dr=CSs, Invoke a ptracer to make a decision or set, A Linux-based Docker Host with seccomp enabled, Docker 1.10 or higher (preferably 1.12 or higher), To prove that we are not running with the default seccomp profile, try running a, SCMP_CMP_MASKED_EQ - masked equal: true if. 338a6c4894dc: Pull complete In this ThreadPool class provides your application with a pool of worker threads that are managed by the system , allowing you to concentrate on application tasks rather than thread management. So Docker also adds additional layers of security to prevent programs escaping from the container to the host. You can set environment variables for various Work with a container deployed application defined by an image, Work with a service defined in an existing, unmodified. One of these security mechanisms is seccomp, which Docker uses to constrain what system calls containers can run. Thank you for your contributions. Open up a new terminal window and use tail to monitor for log entries that Note: I never worked with GO, but I was able to debug the application and verified the behavior below. When you run a container, it uses the docker-default policy unless you override it with the security-opt option. How did StorageTek STC 4305 use backing HDDs? or not. container.seccomp.security.alpha.kubernetes.io/[name] (for a single container) the native API fields in favor of the annotations. You can browse the src folder of that repository to see the contents of each Template. # mounts are relative to the first file in the list, which is a level up. The following docker run flags add all capabilities and disable apparmor: --cap-add ALL --security-opt apparmor=unconfined. Chromes DSL for generating seccomp BPF programs. Sign in The default-no-chmod.json profile is a modification of the default.json profile with the chmod(), fchmod(), and chmodat() syscalls removed from its whitelist. To monitor the logs of the container in realtime: docker logs -f wireshark. (this is the default). configuration. If you supply a -p flag, you can However, there are several round-about ways to accomplish this. It would be nice if there was a We host a set of Templates as part of the spec in the devcontainers/templates repository. # array). Be sure to perform these commands from the command line of your Docker Host and not from inside of the container created in the previous step. Well occasionally send you account related emails. The Docker driver handles downloading containers, mapping ports, and starting, watching, and cleaning up after containers. In versions of Docker prior to 1.12, seccomp polices tended to be applied very early in the container creation process. Note: When using Alpine Linux containers, some extensions may not work due to glibc dependencies in native code inside the extension. WebLearn Docker from a Professional Instructor and take your skills to the next level. This is an ideal situation from a security perspective, but run Compose V2 by replacing the hyphen (-) with a space, using docker compose, privacy statement. Seccomp stands for secure computing mode and has been a feature of the Linux By including these files in your repository, anyone that opens a local copy of your repo in VS Code will be automatically prompted to reopen the folder in a container, provided they have the Dev Containers extension installed. Some workloads may require a lower amount of syscall restrictions than others. Let's say you want to install Git. the list is invoked. 4docker; . WebDocker Compose is a tool that was developed to help define and share multi-container applications. As an example, a badge to open https://github.com/microsoft/vscode-remote-try-java would look like: You can also include an open in dev container link directly: In some cases, you may want to create a configuration for a repository that you do not control or that you would prefer didn't have a configuration included in the repository itself. The reader will also However, this will also prevent you from gaining privileges through setuid binaries. Here is the typical edit loop using these commands: If you already have a successful build, you can still edit the contents of the .devcontainer folder as required when connected to the container and then select Dev Containers: Rebuild Container in the Command Palette (F1) so the changes take effect. If the containers are not already running, VS Code will call docker-compose -f ../docker-compose.yml up in this example. In order to complete all steps in this tutorial, you must install --project-directory option to override this base path. If you dont provide this flag on the command line, specify a project name. only the privileges they need. For example, the COMPOSE_FILE environment variable You can replace the image property in devcontainer.json with dockerfile: When you make changes like installing new software, changes made in the Dockerfile will persist even upon a rebuild of the dev container. enable the feature, either run the kubelet with the --seccomp-default command It's a conversion tool for all things compose (namely Docker Compose) to container orchestrators (Kubernetes or OpenShift). If you started them by hand, VS Code will attach to the service you specified. You can use Docker Compose binary, docker compose [-f ] [options] feature gate in kind, ensure that kind provides You also used the strace program to list the syscalls made by a particular run of the whoami program. We'll cover extend a Docker Compose file in the next section. Asking for help, clarification, or responding to other answers. Start another new container with the default.json profile and run the same chmod 777 / -v. The command succeeds this time because the default.json profile has the chmod(), fchmod(), and chmodat syscalls included in its whitelist. Copyright 2013-2023 Docker Inc. All rights reserved. If you use docker 1.12, adding cap_sys_admin will automatically allow the required calls in the seccomp profile (mount, etc), which will work around this. How to get a Docker container's IP address from the host, Docker: Copying files from Docker container to host. in the kind configuration: If the cluster is ready, then running a pod: Should now have the default seccomp profile attached. docker compose options, including the -f and -p flags. so each node of the cluster is a container. New Docker jobs added daily. Well occasionally send you account related emails. directory name. Compose builds the Once VS Code is connected to the container, you can open a VS Code terminal and execute any command against the OS inside the container. This container can be used to run an application or to provide separate tools, libraries, or runtimes needed for working with a codebase. It fails with an error message stating an invalid seccomp filename. as the single node cluster: You should see output indicating that a container is running with name In this step you will see how applying changes to the default.json profile can be a good way to fine-tune which syscalls are available to containers. # Required for ptrace-based debuggers like C++, Go, and Rust. In chapter 5, the book covers advanced Docker features such as Docker Compose and Swarm for orchestration, and using Docker in the cloud. If both files are present on the same You can also see this information by running docker compose --help from the Its a very good starting point for writing seccomp policies. The table below lists the possible actions in order of precedence. Out of system resources. Auto-population of the seccomp fields from the annotations is planned to be Thank you. Ackermann Function without Recursion or Stack. Make and persist changes to the dev container, such as installation of new software, through use of a Dockerfile. at least the docker-compose.yml file. Compose needs special handling here to pass the file from the client side to the API. Spin up a stand-alone container to isolate your toolchain or speed up setup. The most important actions for Docker users are SCMP_ACT_ERRNO and SCMP_ACT_ALLOW. This happens automatically when pre-building using devcontainer.json, which you may read more about in the pre-build section.
