aerth/godev repository overview

⁠go development container

• vim-go (auto-complete and more)
• tmux
• bash
• gcc (builds CGO programs against musl lib)

⁠debugging tools

• dlv
• valgrind
• gdb
• file

⁠usage

By default, GoDev creates a directory to be shared with the container in ./data, relative to current working directory. You may want to change this behavior.

You can also edit the launcher script to add port forwarding etc

Change line 2 of the GoDev launcher script to this:

GODEV_SHARED_DIR=$PWD

Or always use the same directory, regardless of from where it is being ran.

export GODEV_SHARED_DIR=$HOME/src

Note: since you are user root in the container, we chown the shared dirctory when exiting the session. This could take a while or lead to unexpected results if the shared directory is not even owned by the user, for example, /.

It's safer to use a dedicated shared directory such as $PWD/data by using the GODEV_SHARED_DIR variable in ~/.bashrc or editing the GoDev launcher script.

⁠installation

• wget -O GoDev https://raw.githubusercontent.com/aerth/godev/master/GoDev
• chmod +x GoDev

finally, move GoDev to /usr/local/bin/ or somewhere in $PATH

⁠notes

No point setting CGO_ENABLED=0 by default. To make static compiled non-cgo programs:

• export CGO_ENABLED=0

Or:

• export GOFLAGS=-tags=osusergo,netgo

Or if using CGO, something like this in your Makefile

buildflags += --ldflags '-linkmode external -extldflags "-static"'
test:
        go build -v $(buildflags) -o $@

The image comes out to 1.25 GB
