What is this?

• A container based on Ubuntu for developing cloud based applications in Go with CoC.nvim or VSCode

Terminal (CoC.nvim)

Using a Pre-built Container

• To use a nightly, pre-built container for linux/amd64 or linux/arm64:

docker run --rm -it -v ${PWD}:/home/nonroot/workspaces/dev-container mperel/dev-container

or

podman run --rm --userns=keep-id -it -v ${PWD}:/home/nonroot/workspaces/dev-container docker.io/mperel/dev-container

Building From Scratch

• By default, the container runs as a nonroot user (as a sudoer) with UID and GID = 1000. This user exists so that if you map a volume, file permissions will not be root. On MacOS, you do not need to change these values. On Linux, if you are not using the first user on your machine, you should change these values to match your current UID and GID. Either way, the following build command will work (change TARGETPLATFORM):

docker build -f .devcontainer/Dockerfile --build-arg TARGETPLATFORM=<either linux/amd64 or linux/arm64> --build-arg USER_UID=$(id -u) --build-arg USER_GID=$(id -g) -t mperel/dev-container .devcontainer

• If you would like to build for all platforms, use docker buildx

docker buildx build -f .devcontainer/Dockerfile --platform linux/arm64,linux/amd64 -t mperel/dev-container .devcontainer

IDE (VSCode)

Using a Pre-built Container

• In your project, copy .devcontainer/devcontainer.json
• Add .devcontainer/Dockerfile with the contents FROM mperel/dev-container
• In the command palette, run Remote-Containers: Reopen in Container
• In the command palette, run Go: Install/Update tools
