Shell scripts package to the containers native interface BalenaOS for the Raspberry Pi.
npm install balena-cloud-appsWithin an open source application, like balena-sound, wifi-repeater, install this module:
``Shell`
#!/usr/bin/env bash
cd application
printf "%s\n" "nodeLinker: node-modules" | tee -a .yarnrc.yml
yarn add balena-cloud-apps
) take variable names %%templates_var%% that are replaced by ther value in
Make changes to the Dockerfile.template files.Initialize .env and package.json:
post_install
> It will scan for any Docker files in the sub-folders and reset package.json,
and files.$3
Complete common definitions (leading and trailing ( spaces ) when defining arrays !!):
`common.env
BALENA_PROJECTS=( MY/PATH MY/RELATIVE/PATH )
BALENA_PROJECTS_FLAGS=( BALENA_MACHINE_NAME MY_VARIABLE )
`
Define architectures:
An ARM computer units like Raspberry PI use (or aarch64.env if it's deployed on a 64 bits platform), desktop units are often x86_64.env:
`x86_64.env
BALENA_ARCH=x86_64
BALENA_MACHINE_NAME=intel-nuc
IMG_TAG=latest
PRIMARY_HUB=docker-hub-balenalib-repo\\/container-servìce-image
`Test
Run unit tests on local host or CI yarn test
$3
Docker Image dependencies are required to validate test units. Theses dependencies include build images needed by Docker based environments:
- Docker and Balena Cloud platform (DockerHub, etc.)
- CircleCI, TravisCI, etc.First login to Docker or Balena, if you already have an account or create one.
docker login or balena login
The folder
contains Dockerfile templates that maybe pulled from Docker. balena_deploy test/build/
Finally select the corresponding architecture
ARM32, ARM64 bits or X86-64 (choose 1, 2 or 3) and choose to build dependenciesIt takes a few minutes for the docker machine to pull, update local images and to push them to the repository. They take the name
and get a public URL at https://hub.docker.com/r/$DOCKER_USER/balena_deploy .
You can build locally:
docker_build . .
In BASH scripts, use arguments:
balena_deploy . x86_64 --nobuild --exit
balena_deploy . armhf --balena
Basically, commit all your changes and bump to the next version, then push tags:
# version string without the leading "v."
npm version "0.0.1"
git push --tags
The continuous integration system will detect the new version tag and deploy to NPMJS if all build steps succeed.
