alpine-quasar

Legacy Image

This image still uses the old-style format for Dockerfiles/makefile recipes, that may (or may not) be compatible with the newer image sources. The container should keep working as expected, but for building new images, a significant part of the code needs to be updated.

Container for Alpine Linux + S6 + NodeJS + VueJS + Quasar Framework CLI

This image containerizes the command line client for Quasar Framework and VueJS CLI along with its NPM dependencies.

Based on Alpine Linux from the vue image with the @quasar/cli package installed in it.

Get the Image¶

Docker Hub

Pull the image from Docker Hub.

docker pull woahbase/alpine-quasar

Image Tags

The image is tagged respectively for the following architectures,

x86_64

latest tag is retagged from x86_64, so pulling without any tag fetches you that image. For any other architectures specify the tag for that architecture. e.g. for armv8 or aarch64 host it is alpine-quasar:aarch64.

Run¶

We can call quasar commands directly on the container, or run bash in the container to get a user-scoped shell,

commandshell

docker run --rm -it \
  --name docker_quasar \
  --workdir /home/alpine/project \
  -p 8080:8080 \
  -v $PWD:/home/alpine/project \
woahbase/alpine-quasar:x86_64 \
  --version

docker run --rm -it \
  --entrypoint /bin/bash \
  --name docker_quasar \
  --workdir /home/alpine/project \
  -p 8080:8080 \
  -v $PWD/project:/home/alpine/project \
woahbase/alpine-quasar:x86_64

Configuration¶

Mount the project directory (where package.json is) at /home/alpine/project. Mounts PWD by default.
Quasar runs under the user alpine.

Common Recipes¶

The usual quasar stuff. e.g

initdevbuild

Initialize projects with

docker run --rm -it \
  --name docker_quasar \
  -v $PWD:/home/alpine/project \
woahbase/alpine-quasar:x86_64 \
  init

Run the dev server,

docker run --rm -it \
  --name docker_quasar \
  -v $PWD:/home/alpine/project \
  -p 8080:8080 \
woahbase/alpine-quasar:x86_64 \
  dev -m pwa -t mat

Build the project with

docker run --rm -it \
  --name docker_quasar \
  -v $PWD:/home/alpine/project \
woahbase/alpine-quasar:x86_64 \
  build -m pwa -t mat

Build Your Own¶

Feel free to clone (or fork) the repository and customize it for your own usage, build the image for yourself on your own systems, and optionally, push it to your own public (or private) repository.

Here's how...

Setting up¶

Before we clone the /repository, we must have Git, GNU make, and Docker (optionally, with buildx plugin for multi-platform images) setup on the machine. Also, for multi-platform annotations, we might require enabling experimental features of Docker.

Now, to get the code,

Github

Clone the repository with,

git clone https://github.com/woahbase/alpine-quasar
cd alpine-quasar

Always Check Before You Make!

Did you know, we could check what any make target is going to execute before we actually run them, with

make -n <targetname> <optional args>

Build and Test¶

To create the image for your architecture, run the build and test target with

make build test

For building an image that targets another architecture, it is required to specify the ARCH parameter when building. e.g.

x86_64

make build test ARCH=x86_64

Make to Run¶

Running the image creates a container and either starts a service (for service images) or provides a shell (can be either a root-shell or usershell) to execute commands in, depending on the image. We can run the image with

make run

But if we just need a root-shell in the container without any fance pre-tasks (e.g. for debug or to test something bespoke), we can run bash in the container with --entrypoint /bin/bash. This is wrapped in the makefile as

make shell

Nothing vs All vs Run vs Shell

By default, if make is run without any arguments, it calls the target all. In our case this is usually mapped to the target run (which in turn may be mapped to shell).

There may be more such targets defined as per the usage of the image. Check the makefile for more information.

Push the Image¶

If the build and test steps finish without any error, and we want to use the image on other machines, it is the next step push the image we built to a container image repository (like /hub), for that, run the push target with

make push

If the built image targets another architecture then it is required to specify the ARCH parameter when pushing. e.g.

x86_64

make push ARCH=x86_64

That's all folks! Happy containerizing!
