Development Container Scripts

This folder contains a set of scripts that can be referenced by Dockerfiles in development container "definitions" that are found under the containers directory. You are also free to use them in your own dev container configurations.

Scripts

Script names end in the Linux distribution "tree" they support. The majority are for Ubuntu/Debian.

• Debian or Ubuntu: -debian
• CentOS, RHEL: -redhat (when the yum package manager is available)
• Alpine Linux: -alpine

Some scripts have special installation instructions (like desktop-lite-debian.sh). Consult the following documents for more information (in order of the script name):

Document	Script
Azure CLI Install Script	azcli-debian.sh
Common Script	common-debian.sh common-alpine.sh common-redhat.sh
Desktop (Lightweight) Install Script	desktop-lite-debian.sh
Docker-from-Docker Install Script	docker-debian.sh docker-redhat.sh
Git Build/Install from Source Script	git-from-src-debian.sh
Git LFS Install Script	git-lfs-debian.sh
GitHub CLI Install Script	github-debian.sh
Go (golang) Install Script	go-debian.sh
Gradle Install Script	gradle-debian.sh
Java Install Script	java-debian.sh
Kubectl and Helm Install Script	kubectl-helm-debian.sh
Maven Install Script	maven-debian.sh
Node.js Install Script	node-debian.sh
PowerShell Install Script	powershell-debian.sh
Python Install Script	python-debian.sh
Ruby Install Script	ruby-debian.sh
Rust (rustlang) Install Script	rust-debian.sh
SSH Server Install Script	sshd-debian.sh
Terraform CLI Install Script	terraform-debian.sh

Using a script

See the documentation above for specific instructions on individual scripts. This section will outline some general tips for alternate ways to reference the scripts in your Dockerfile.

Copying the script to .devcontainer/library-scripts

The easiest way to use a script is to simply copy it into a .devcontainers/library-scripts folder. From here you can then use the script as follows in your Dockerfile:

Debian/Ubuntu

COPY library-scripts/*.sh /tmp/library-scripts/
RUN bash /tmp/library-scripts/common-debian.sh

Generally it's also good to clean up after running a script in the same RUN statement to keep the "layer" small.

COPY library-scripts/*.sh /tmp/library-scripts/
RUN bash /tmp/library-scripts/common-debian.sh
    && apt-get clean -y && rm -rf /var/lib/apt/lists/* /tmp/library-scripts

Alpine

COPY library-scripts/*.sh /tmp/library-scripts/
RUN ash /tmp/library-scripts/common-alpine.sh \
    && rm -rf /tmp/library-scripts

CentOS/RedHat/Oracle Linux

COPY library-scripts/*.sh /tmp/library-scripts/
RUN bash /tmp/library-scripts/common-redhat.sh \
    && yum clean all && rm -rf /tmp/library-scripts

Note that the CI process for this repository will automatically keep scripts in the .devcontainers/library-scripts folder up to date for each definition in the containers folder.

Downloading the script with curl / wget instead

If you prefer, you can download the script using curl or wget and execute it instead. This can convenient to do with your own Dockerfile, but is generally avoided for definitions in this repository. To avoid unexpected issues, you should reference a release specific version of the script, rather than using master. For example:

RUN bash -c "$(curl -fsSL "https://raw.githubusercontent.com/microsoft/vscode-dev-containers/v0.131.0/script-library/common-debian.sh")" \
    && apt-get clean -y && rm -rf /var/lib/apt/lists/*

Or if you're not sure if curl is installed:

RUN apt-get update && export DEBIAN_FRONTEND=noninteractive  \
    && apt-get -y install --no-install-recommends curl ca-certificates \
    && bash -c "$(curl -fsSL "https://raw.githubusercontent.com/microsoft/vscode-dev-containers/v0.131.0/script-library/common-debian.sh")" \
    && apt-get clean -y && rm -rf /var/lib/apt/lists/*

As before, the last line is technically optional, but minimizes the size of the layer by removing temporary contents.

You can also use wget:

RUN apt-get update && export DEBIAN_FRONTEND=noninteractive  \
    && apt-get -y install --no-install-recommends wget ca-certificates \
    && bash -c "$(wget -qO- "https://raw.githubusercontent.com/microsoft/vscode-dev-containers/v0.131.0/script-library/common-debian.sh")" \
    && apt-get clean -y && rm -rf /var/lib/apt/lists/*

Arguments

Some scripts include arguments that you can allow developers to set by using ARG in your Dockerfile.

Using arguments with scripts from the .devcontainers/library-scripts folder

In this case, you can simply pass in the arguments to the script.

# Options for script
ARG INSTALL_ZSH="true"

COPY library-scripts/*.sh /tmp/library-scripts/
RUN /bin/bash /tmp/library-scripts/common-debian.sh "${INSTALL_ZSH}" "vscode" "1000" "1000" "true" \
    && apt-get clean -y && rm -rf /var/lib/apt/lists/* /tmp/library-scripts

Using arguments when downloading with curl

The trick here is to use the double-dashes (--) after the bash -c command and then listing the arguments.

# Options for script
ARG INSTALL_ZSH="true"

# Download script and run it with the option above
RUN apt-get update && export DEBIAN_FRONTEND=noninteractive  \
    && apt-get -y install --no-install-recommends curl ca-certificates \
    && bash -c "$(curl -fsSL "https://raw.githubusercontent.com/microsoft/vscode-dev-containers/v0.131.0/script-library/common-debian.sh")" -- "${INSTALL_ZSH}" "vscode" "1000" "1000" "true" \
    && apt-get clean -y && rm -rf /var/lib/apt/lists/*

Testing

The test sub-folder includes Debian, Alpine, and RedHat based dev containers that can be used to test the scripts.
