CI/CD¶

Using a CI/CD infrastructure that builds your Linux images can be very helpful for developers.

Set up CI/CD infrastructure (Gitlab)

Set up a job to build an image¶

Create a dedicated repository cloned from ours:

git clone git@gitlab.com:witekio/rnd/theembeddedkit/welma/ci.git

Add your jobs in a branch:

git checkout --orphan config/demo-onboarding

Edit your .gitlab-ci.yml (use Welma helpers from branch main):

.gitlab-ci.yml:

include:
  - project: ${CI_PROJECT_PATH}
    file: /snippets/welma.yml
    ref: 23034130bf0f444785b5aee851b3455dcb2fccc4

stages:
  - "Build Yocto Image"

.job-build-common:
  image: registry.gitlab.com/witekio/rnd/b0000-witekio-welma/dockerfile-yocto/yocto-ci:kirkstone
  variables:
    MACHINE: sm2s-imx93-mbep5
    SSTATE_DIR: /share/sstate
    DL_DIR: /share/downloads
    GITLAB_PACKAGE_NAME: demo-onboarding
    GITLAB_PACKAGE_VERSION: v1.0
    TEMPLATECONF: meta-demo-onboarding/conf/templates/default
    WELMA_MANIFEST_GIT_URI: git@gitlab.com:witekio/rnd/b0000-witekio-welma/welma-manifest
    WELMA_MANIFEST_GIT_REF: 1.4.2-scarthgap
    WELMA_MANIFEST_FILE: welma-manifest/1.4.2-scarthgap/manifest-${MACHINE}.txt

"build:demo-onboarding":
  extends:
    - .job-welma-build
    - .job-build-common
  stage: "Build Yocto Image"
  variables:
    BITBAKE_RECIPES: demo-image-onboarding-dev

Set up job to build a SDK¶

Create another job for building a SDK:

.gitlab-ci.yml:

...

stages:
  - "Build Yocto Image"
  - "Build SDK"

...

"build:demo-onboarding-sdk":
  extends:
    - .job-welma-build-sdk
    - .job-build-common
  stage: "Build SDK"
  dependencies: [] # prevent the downloading of all build artifacts
  variables:
    BITBAKE_RECIPES: demo-image-onboarding-dev -c populate_sdk
