Swiss Army Container

This repository contains Dockerfiles for creating development environment containers, designed to be ephemeral and support both arm64 and amd64 architectures. The --rm flag is utilized to ensure that containers are removed after use, making them ideal for one-time development tasks. These containers are equipped with a wide range of tools and utilities to facilitate development across multiple languages and platforms, providing a versatile and clean environment each time they are used.

Contents

• Dockerfile.arm64: Dockerfile for image for the arm64 architecture.
• Dockerfile.amd64: Dockerfile for image for the amd64 architecture.

Included Tools

Each Docker image includes a wide array of tools for diverse development needs:

• Basic Utilities: vim, git, curl, wget, zip, unzip, jq, tree, locate, rsync, less, file.
• Languages & Frameworks: Go, Node.js & npm, Python3 with pip and setuptools.
• Containerization Tools: Docker CLI, Docker Compose, Kubernetes tools (kubectl, kubectx, kubens, Krew).
• HashiCorp Stack: Terraform, Vault, Consul, Packer, Boundary, Waypoint.
• Cloud Service CLIs: AWS CLI, Google Cloud CLI, Azure CLI.
• Network Tools: ssh, netcat, iproute2, dnsutils.
• Databases: PostgreSQL, Redis.
• Security Tools: Cosign, Snyk CLI.
• Other Utilities: ZSH with Oh My Zsh, Powerlevel10k, Helm, Infracost, Eksctl, Calicoctl, AWS IAM Authenticator.

Usage

To build the Docker images, use the following commands at the root of the repository:

For arm64:

docker build --build-arg TF_VERSION=0.15.6 -t swissarmycontainer:arm64 .

For amd64:

docker build --build-arg TF_VERSION=0.15.6 -t swissarmycontainer:amd64 .

Running the Container

You can use the following generic command to run the container. Adjust the container name and tag as needed:

docker run -it --rm \
  --hostname swiss \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ${PWD}:/workspace \
  -v $HOME/.ssh:/root/.ssh \
  -w /workspace \
  --name swisscontainer \
  swissarmycontainer:arm64

Setting Up an Alias for Easy Container Access

To simplify the process of starting your container, you can set up an alias. Add the following line to your .bashrc or .zshrc file:

alias swiss='docker run -it --rm \
  --hostname swiss \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ${PWD}:/workspace \
  -v $HOME/.ssh:/root/.ssh \
  -w /workspace \
  --name swisscontainer \
  swissarmycontainer:arm64'

After adding this line, reload your shell configuration with the command source ~/.bashrc (or source ~/.zshrc if you're using Zsh).

Now, you can start your container simply by typing swiss in your terminal.

This alias command will start an interactive session of your swissarmycontainer Docker container with the ARM64 architecture, mapping your current directory and SSH keys into the container for seamless development workflow.

SSH Keys Sharing

To share your SSH keys with the container, mount your .ssh directory as a volume. For MacOS users, remember to comment out the keychain line in your SSH config if present, to ensure compatibility.

-v $HOME/.ssh:/root/.ssh

This command will mount your local .ssh directory to the container's /root/.ssh directory, allowing the container to use your SSH keys.

For MacOS users, if you have issues with SSH key management in the container, ensure your ~/.ssh/config file is appropriately configured. Here's a common setting for MacOS:

Host github.com
  AddKeysToAgent yes
  #UseKeychain yes
  IdentityFile ~/.ssh/your_private_key

If you're experiencing issues, try commenting out the UseKeychain line (add a # at the beginning of the line). This change might be necessary because the keychain access doesn't work inside the Docker container.

Customization

Feel free to customize the Dockerfiles according to your needs by modifying tool versions, adding or removing packages, etc.
