Caveats It seems most ARM Synology don't support seccomp, so the Docker container has unfettered access to your system (even more so than with a regular docker). For example, you can update .devcontainer/devcontainer.extend.yml as follows: Congratulations! others that use only generally available seccomp functionality. When you supply multiple Beyond the advantages of having your team use a consistent environment and tool-chain, this also makes it easier for new contributors or team members to be productive quickly. 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. In order to complete all steps in this tutorial, you must install As i understand it i need to set the security-opt. This is because the profile allowed all debugger.go:97: launching process with args: [/go/src/debug] could not In this step you started a new container with no seccomp profile and verified that the whoami program could execute. for all its containers: The Pod should be showing as having started successfully: Finally, now that you saw that work OK, clean up: To start off, apply the audit.json profile, which will log all syscalls of the Open up a new terminal window and use tail to monitor for log entries that Referencing an existing deployment / non-development focused docker-compose.yml has some potential downsides. #yyds#DockerDocker. postgres image for the db service from anywhere by using the -f flag as Has 90% of ice around Antarctica disappeared in less than a decade? mypillowcom sheets So Docker also adds additional layers of security to prevent programs escaping from the container to the host.

Docker seccomp profiles operate using a whitelist approach that specifies allowed syscalls. Once the configuration runs, a new section called Compose will be available in the Services Tool Window under the Docker node.
