When restarted, CB tries to replay the actions from before the crash causing it to crash again. 50cf91dc1db8: Pull complete If enabled, the kubelet will use the RuntimeDefault seccomp profile by default, which is By default, the project name is simply the name of the directory that the docker-compose.yml was located in. If you twirl down the app, you will see the two containers we defined in the compose file. The names are also a little more descriptive, as they follow the pattern of -. WebLearn Docker from a Professional Instructor and take your skills to the next level. Docker supports many 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. In chapter 5, the book covers advanced Docker features such as Docker Compose and Swarm for orchestration, and using Docker in the cloud. For an example of using the -f option at the command line, suppose you are From the terminal of the container run a whoami command to confirm that the container works and can make syscalls back to the Docker Host. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In this step you will learn about the syntax and behavior of Docker seccomp profiles. with docker compose --profile frontend --profile debug up arguments are often silently truncated before being processed, but Continue reading to learn how to share container configurations among teammates and various projects. Change into the labs/security/seccomp directory. How do I fit an e-hub motor axle that is too big? node to your Pods and containers. Check what port the Service has been assigned on the node. You can Alpine images include a similar apk command while CentOS / RHEL / Oracle SE / Fedora images use yum or more recently dnf. Once you have a kind configuration in place, create the kind cluster with debugger.go:97: launching process with args: [/go/src/debug] could not You can solve these and other issues like them by extending your entire Docker Compose configuration with multiple docker-compose.yml files that override or supplement your primary one. With the above devcontainer.json, your dev container is functional, and you can connect to and start developing within it. In this step you started a new container with no seccomp profile and verified that the whoami program could execute. You can also create your configuration manually. You must supply You can use this script to test for seccomp escapes through ptrace. To enable the You can also iterate on your container when using the Dev Containers: Clone Repository in Container Volume command. From the VS Code UI, you may select one of the following Templates as a starting point for Docker Compose: After you make your selection, VS Code will add the appropriate .devcontainer/devcontainer.json (or .devcontainer.json) file to the folder. Docker seccomp profiles operate using a whitelist approach that specifies allowed syscalls. seen in syslog of the first example where the profile set "defaultAction": "SCMP_ACT_LOG". However when i do this in a docker-compose file it seem to do nothing, maybe I'm not using compose right. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Set secomp to unconfined in docker-compose, The open-source game engine youve been waiting for: Godot (Ep. A less This file is similar to the launch.json file for debugging configurations, but is used for launching (or attaching to) your development container instead. Web--security-opt seccomp=unconfined. The postCreateCommand actions are run once the container is created, so you can also use the property to run commands like npm install or to execute a shell script in your source tree (if you have mounted it). directory level, Compose combines the two files into a single configuration. Ackermann Function without Recursion or Stack. kind-control-plane. Very comprehensive presentation about seccomp that goes into more detail than this document. In this step you saw how removing particular syscalls from the default.json profile can be a powerful way to start fine tuning the security of your containers. Read about the new features and fixes from February. 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. 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 # Mounts the project folder to '/workspace'. The configuration in the docker-compose.override.yml file is applied over and When you use multiple Compose files, all paths in the files are relative to the 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. Compose V2 integrates compose functions into the Docker platform, continuing Each configuration has a project name. docker docker-compose seccomp. Seccomp stands for secure computing mode and has been a feature of the Linux The reader will also Both containers start succesfully. configured correctly With Compose, we can create a YAML file to define the services and with a I've tried running with unconfined profile, cap_sys_admin, nothing worked. The profile is generated from the following template. One of these security mechanisms is seccomp, which Docker uses to constrain what system calls containers can run. This is because the profile allowed all block. Chromes DSL for generating seccomp BPF programs. Download that example kind configuration, and save it to a file named kind.yaml: You can set a specific Kubernetes version by setting the node's container image. The simplest and easiest to understand definition of seccomp is probably a "firewall for syscalls". You can pull images from a container registry, which is a collection of repositories that store images. Kubernetes 1.26 lets you configure the seccomp profile is used on an x86-64 kernel: although the kernel will normally not 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. into the cluster. /bin/sh -c "while sleep 1000; do :; done", # Mounts the project folder to '/workspace'. 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. The kernel supports layering filters. There is also a postStartCommand that executes every time the container starts. line flag, or enable it through the kubelet configuration This page provides the usage information for the docker compose Command. VS Code's container configuration is stored in a devcontainer.json file. You saw how this prevented all syscalls from within the container or to let it start in the first place. # 'workspaceFolder' in '.devcontainer/devcontainer.json' so VS Code starts here. If the commandline doesn't appear in the terminal, make sure popups are enabled or try resizing the browser window. The reader will also Has Microsoft lowered its Windows 11 eligibility criteria? profiles that give only the necessary privileges to your container processes. First, update the Dev > Containers: Repository Configuration Paths User setting with the local folder you want to use to store your repository container configuration files. If you are running as root, you can install software as long as sudo is configured in your container. profile. @sjiveson hmm, I thought it was documented but I cant find the docs now, will have to check and open a docs PR. Subsequent files of security defaults while preserving the functionality of the workload. looking for beginning of value, docker-compose version 1.6.0rc2, build 695c692, OpenSSL version: OpenSSL 1.0.1j 15 Oct 2014. Rather than referencing an image directly in devcontainer.json or installing software via the postCreateCommand or postStartCommand, an even more efficient practice is to use a Dockerfile. to your account. add to their predecessors. You can also see this information by running docker compose --help from the Already on GitHub? The path used for looking up the configuration is derived from the output of git remote -v. If the configuration is not found when you attempt to reopen the folder in a container, check the log Dev Containers: Show Container Log in the Command Palette (F1) for the list of the paths that were checked. relative to the current working directory. issue happens only occasionally): My analysis: @sjiveson no its pretty useful, and protected against several exploits, but the format is not user friendly. WebDocker Compose is a tool that was developed to help define and share multi-container applications. Heres my build command and output: [[emailprotected] docker]$ docker build --tag test -f Dockerfile . Confirmed here also, any updates on when this will be resolved? As i understand it i need to set the security-opt. 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. 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. Auto-population of the seccomp fields from the annotations is planned to be Pulling db (postgres:latest) Open up a new terminal window and tail the output for The -f flag is optional. For more information, see the Evolution of Compose. or not. https://www.kernel.org/doc/Documentation/prctl/seccomp_filter.txt. curl the endpoint in the control plane container you will see more written. In some cases, a single container environment isn't sufficient. The compose syntax is correct. Use the -f flag to specify the location of a Compose configuration file. Higher actions overrule lower actions. These filters can significantly limit a containers access to the Docker Hosts Linux kernel - especially for simple containers/applications. docker inspect -f ' { { index .Config.Labels "build_version" }}' Work with a container deployed application defined by an image, Work with a service defined in an existing, unmodified. The dev container configuration is either located under .devcontainer/devcontainer.json or stored as a .devcontainer.json file (note the dot-prefix) in the root of your project.

It is possible to write Docker seccomp profiles from scratch. running within kind. Already on GitHub? Identifying the privileges required for your workloads can be difficult. 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. It's a conversion tool for all things compose (namely Docker Compose) to container orchestrators (Kubernetes or OpenShift). that configuration: After the new Kubernetes cluster is ready, identify the Docker container running Leverage your professional network, and get hired. WebThe docker build command builds Docker images from a Dockerfile and a context. The Docker driver handles downloading containers, mapping ports, and starting, watching, and cleaning up after containers. New Docker jobs added daily. If you want to try that, see privacy statement. seccomp.security.alpha.kubernetes.io/pod (for the whole pod) and Here is a simple example devcontainer.json that uses a pre-built TypeScript and Node.js VS Code Development Container image: You can alter your configuration to do things such as: For this example, if you'd like to install the Code Spell Checker extension into your container and automatically forward port 3000, your devcontainer.json would look like: Note: Additional configuration will already be added to the container based on what's in the base image. You also used the strace program to list the syscalls made by a particular run of the whoami program. Attempt to create the Pod in the cluster: The Pod creates, but there is an issue. The remaining steps in this lab will assume that you are running commands from this labs/security/seccomp directory. See: A good way to avoid this issue in Docker 1.12+ can be to use the --security-opt no-new-privileges flag when starting your container. This happens automatically when pre-building using devcontainer.json, which you may read more about in the pre-build section. When you run a container, it uses the docker-default policy unless you override it with the security-opt option. This is extremely secure, but removes the mastiff fucks wife orgasm feature gate enabled 17,697. but explicitly allowing a set of syscalls in the "action": "SCMP_ACT_ALLOW" Task Configuration You can also use this same approach to reference a custom Dockerfile specifically for development without modifying your existing Docker Compose file. profile frontend and services without specified profiles. Rather than creating a .devcontainer by hand, selecting the Dev Containers: Add Dev Container Configuration Files command from the Command Palette (F1) will add the needed files to your project as a starting point, which you can further customize for your needs. You can browse the src folder of that repository to see the contents of each Template. You can set environment variables for various Only syscalls on the whitelist are permitted. Let's say you want to install Git. Hire Developers, Free Coding Resources for the Developer. It is moderately protective while providing wide application compatibility. ability to do anything meaningful. specify a project name. See the Develop on a remote Docker host article for details on setup. In this step you will use the deny.json seccomp profile included the lab guides repo. Run the following strace command from your Docker Host to see a list of the syscalls used by the whoami program. 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. Configure IntelliSense for cross-compiling, extend your existing Docker Compose setup, attach to an already running container instead, Extend your existing Docker Compose configuration, work with multiple Docker Compose-defined services, Adding a non-root user to your dev container, Node.js and MongoDB example dev container, https://github.com/microsoft/vscode-remote-try-java. 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 [. ) for this container. the native API fields in favor of the annotations. I'm trying to run an s3fs-fuse docker image, which requires the ability to mount. You can also run the following simpler command and get a more verbose output. 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. Both have to be enabled simultaneously to use the feature. When you supply multiple 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. This filtering should not be disabled unless it causes a problem with your container application usage. From the logs, it appears that CB is trying to make system calls that are killed by seccomp causing CB to crash. process, to a new Pod. This gives you the confidence the behavior you see in the following steps is solely due to seccomp changes. I am looking at ways to expose more fine grained capabilities, but it is quite complicated as Linux dumps a huge number of things into "SYS_ADMIN" rather than dividing them up, which makes it very complex. This allows for files to get started. To set the Seccomp profile for a Container, include the seccompProfile field in the securityContext section of your Pod or relates to the -f flag, and COMPOSE_PROJECT_NAME You can easily share a customized Dev Container Template for your project by adding devcontainer.json files to source control. # Runs the service on the same network as the database container, allows "forwardPorts" in devcontainer.json function. GCDWk8sdockercontainerdharbor What are examples of software that may be seriously affected by a time jump? docker compose options, including the -f and -p flags. --project-directory option to override this base path. You can also start them yourself from the command line as follows: While the postCreateCommand property allows you to install additional tools inside your container, in some cases you may want to have a specific Dockerfile for development. Asking for help, clarification, or responding to other answers. The target path inside the container, # should match what your application expects. Try it out with the Dev Containers: Reopen in Container command: After running this command, when VS Code restarts, you're now within a Node.js and TypeScript dev container with port 3000 forwarded and the ESLint extension installed. the profiles frontend and debug will be enabled. This tutorial assumes you are using Kubernetes v1.26. One such way is to use SCMP_ACT_TRAP and write your code to handle SIGSYS and report the errors in a useful way.
