GitHub Actions workflow

Some important changes to GitHub Actions workflows:

  1. golangci-lint
  2. Docker build secrets

golangci-lint and its builder (golangci-lint-action v8.0.0)

The Go extension for Visual Studio Code supports golangci-lint albeit through the “Go” debug console. An advantage of accessing it in Visual Studio Code is that recommendations hyperlink to the code.

I’ve added golangci-lint to most of my repos’ GitHub Actions workflows. Belatedly, I realized it should run before not in parallel with the e.g. container builder.

Golang, Containers and private repos

A smörgåsbord of guidance involving Golang modules, private repos and containers. Everything herein is documented elsewhere (I’ll provide links) but I wanted to consolidate the information primarily for my own benefit.

GOPRIVATE

Using private modules adds complexity because builders need to be able to access private modules. Customarily, as you’re hacking away, you’ll likely not encounter issues but, when you write a Dockerfile or develop some CI, you’ll encounter something of the form:

Don't ignore the (hidden) ignore files

Don’t forget to add appropriate ignore files…

  • .dockerignore when using Docker
  • .gitignore when using git
  • .gcloudignore when using Google Cloud Platform

This week, I’ve been bitten twice in not using these.

They’re hidden files and so they’re more easy to forget unfortunately.

.dockerignore

docker build ...

Without .dockerignore

Sending build context to Docker daemon  229.9MB

Because, even though Rust’s cargo creates a useful .gitignore, it doesn’t create .dockerignore and, as you as you create ./target, you’re going to take up (likely uncessary) build context space:
