Purpose

This is a series of pre-built Devcontainer image to allow local development.

Features

• Cobra CLI
• Temporal Cloud CLI

Images

There are a number of images that exist.

Base

ghcr.io/mrsimonemms/devcontainers/base

This provides a base image to use for all your development environment need. This is an Ubuntu image with sensible defaults, including the best-looking Git diffs, Docker support, tab-completion and useful Git aliases.

Full

ghcr.io/mrsimonemms/devcontainers/full

An image with some modern tooling installed.

• Go ✅
• Kubernetes, Helm and Minikube ✅
• Kubectx ✅
• K9s ✅
• Node.js ✅
• Pre-Commit ✅
• Python ✅

The advantage of using this image is that the features are pre-built which shifts the build effort into GitHub Actions rather than on your local machine.

This can be easily extended with additional features by adding them to your .devcontainer/devcontainer.json file.

This is built to both linux/amd64 and linux/arm64 to cover use with both a "standard" 64 bit machine and a modern Mac.

Both Homebrew and Nix were in the original builds, but I found that I rarely (if ever) used them in my devcontainers so removed them. This reduced the image size by around 2.5GB. These are also not supported by the linux/arm64 platform.

Temporal Min

ghcr.io/mrsimonemms/devcontainers/temporal_min

An image designed to make working with Temporal easier with the minimum Temporal dependencies installed. This image should be used for all Temporal work and adding the required features in your .devcontainer/devcontainer.json.

• Pre-Commit ✅
• Poetry ✅
• Python ✅
• Temporal CLI ✅

Temporal Full

ghcr.io/mrsimonemms/devcontainers/temporal_full

An image designed to make working with Temporal easier, with native support for all official SDKs.

• Dotnet
• Go ✅
• Java ✅
• Node.js ✅
• PHP ✅
• Pre-Commit ✅
• Poetry ✅
• Python ✅
• Ruby ✅
• Temporal CLI ✅

This image is quite large. Unless full support for everything is required, use the Temporal Min image and adding the required features in your .devcontainer/devcontainer.json.

Usage

These images can be used in any way that Dev Containers supports. Typically, this would be by specifying the image in your devcontainer.json file:

{
  "name": "devcontainer",
  "image": "ghcr.io/mrsimonemms/devcontainers/full"
}

As this image is pre-built, it will vastly speed up your workflow.
