Go image size could be reduced

Bug description

The go image weights around 2.8 GB. By running go clean -cache -modcache after installing go tools, it could be reduced to 2 GB.

Steps to reproduce

From the chunks/lang-go,

  • run docker build --build-arg base=gitpod/workspace-base:2023-07-20-19-56-24 --build-arg GO_VERSION=1.20.6 -t workspace-go:before .
  • update the Dockerfile by adding go clean -cache -modcache after the go tools installation :
...
&& go install -v honnef.co/go/tools/cmd/staticcheck@latest \
&& go clean -cache -modcache
  • run docker build --build-arg base=gitpod/workspace-base:2023-07-20-19-56-24 --build-arg GO_VERSION=1.20.6 -t workspace-go:after.
  • run docker images
  • compare workspace-go:before and workspace-go:after

Expected behavior

The image could be smaller.

Hey there @osechet, and thanks for the suggestion. From my perspective, it makes sense to remove all the tool cache and I will be raising a PR shortly.
