Go

Curated name go. Installs the Go toolchain via the upstream devcontainers/features/go feature, including golangci-lint.

Add it

monoceros init acme --with-languages=go
monoceros add-language acme go:1.24

Remove it

monoceros remove-language acme go

Or delete the entry from acme.yml by hand and re-run monoceros apply acme - the yml is the source of truth.

Pinning a version

monoceros add-language acme go:1.24

Supported: 1.24, 1.23 (also latest).

Builds stay fast across rebuilds

A Go build is only slow once. The build cache and the module cache live in a volume shared by every workbench on the machine, so a dependency is downloaded and compiled one time and then reused - by the next build, by the next workbench, and after a monoceros apply recreates the container. On a mid-sized project that is well over two gigabytes you do not pay for twice.

The tools a project installs itself stay per workbench:

go install golang.org/x/vuln/cmd/govulncheck@v1.3.0

That lands in ~/go/bin, which is bound to your workbench directory and survives a rebuild, so a make dev-tools-style setup step is a one-time thing rather than something you repeat after every apply. Per workbench on purpose: two projects can pin different versions of the same linter, and one shared directory would only hold one of them. ~/go/bin also comes first on PATH, ahead of the tools the upstream feature ships in /go/bin, so your pinned version is the one that runs.

This needs runtime 1.6.2 or newer. Run monoceros upgrade to move an older workbench up.

Key options

Set these by adding the feature directly (see Other feature options):

Option	Default	Notes
`version`	`latest`	Pin via the `:version` suffix instead.
`golangciLintVersion`	`latest`	Pin the linter version.
