Some x86_64 hosts have issues running rdesktop based images even with the latest docker version due to syscalls that are unknown to docker. You can easily share a customized Dev Container Template for your project by adding devcontainer.json files to source control. 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. In this document, we'll go through the steps for creating a development (dev) container in VS Code: After any of the steps above, you'll have a fully functioning dev container, and you can either continue to the next step of this tutorial to add more features, or stop and begin working in the dev environment you currently have. 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. Lifecycle scripts Have a question about this project? surprising example is that if the x86-64 ABI is used to perform a removed in a future release. It fails with an error message stating an invalid seccomp filename. use a command like docker compose pull to get the Use docker exec to run the curl command within the Referencing an existing deployment / non-development focused docker-compose.yml has some potential downsides.
