Coder Workspace Images

This repository contains Dockerfiles for building Coder workspace images across two distributions: Ubuntu 24.04 and UBI 9.6.

Image Structure

All images are built in layers:

1. Base Images (coder-base-*) - Minimal foundation with essential tools
2. Specialized Images - Built on top of base images with specific tooling

Infrastructure Images

Built on coder-base-* images for DevSecOps, SRE, and SysAdmin workflows.

coder-infra-devops-*

A complete DevOps/SRE toolkit combining all essential infrastructure tools:

• Cloud CLIs: AWS CLI (v2), Google Cloud CLI (gcloud), Azure CLI
• Kubernetes: kubectl, Helm, k9s, kubectx/kubens, kustomize, stern
• Infrastructure as Code: Terraform, OpenTofu, Terragrunt, tflint, tfsec
• Version Control: GitHub CLI (gh)
• Python Tools: aws-shell, boto3
• Standard CLI Tools: vim, nano, less, jq, and more

Note: OpenShift CLI tools (oc, openshift-install) temporarily disabled due to build issues.

Image Naming Convention

Images are published to GitHub Container Registry and follow the pattern: ghcr.io/ausbru87/coder-<category>-<tool>-<distro>:<version>

Examples:

• ghcr.io/ausbru87/coder-datasci-python-ubuntu:24.04
• ghcr.io/ausbru87/coder-dev-go-ubi9:9.6
• ghcr.io/ausbru87/coder-infra-k8s-ubuntu:24.04

All images also have a :latest tag pointing to the most recent build.

Building Images

Images are automatically built and pushed to GitHub Container Registry via GitHub Actions when changes are pushed to the main branch.

Manual Build

To build individual images locally:

cd datasci/python
docker build -f ubuntu.Dockerfile -t ghcr.io/ausbru87/coder-datasci-python-ubuntu:24.04 .

Using Images

Pull images from GitHub Container Registry:

docker pull ghcr.io/ausbru87/coder-datasci-python-ubuntu:latest

Distribution Differences

Ubuntu 24.04

• Debian-based, uses apt package manager
• Python 3.12
• Most widely supported for third-party software
• Best for general development workloads

UBI 9.6 (Red Hat Universal Base Image)

• Enterprise-focused, RPM-based
• Python 3.12
• Suitable for environments requiring RHEL compatibility
• Best for enterprise deployments and Red Hat ecosystems

User Setup

All images run as user coder (UID 1000) with passwordless sudo access.

CI/CD

Images are automatically built and published using GitHub Actions:

• Build Workflow: Triggered on pushes to main branch or manually via workflow dispatch
• Test Workflow: Validates image functionality on pull requests
• Registry: All images are published to GitHub Container Registry (ghcr.io)

License

These images are built using open-source tools and base images. Please refer to individual tool licenses for usage terms.
