Common utilities for Camptocamp CI
Project description
C2C CI utils
Publishing
The main goals of C2C CI utils is to offer the commands to publish the project, see the documentation.
Changelog
When we create a tag by default with the changelog workflow a release is created on GitHub, a changelog is
generated and added to the release.
Checks
C2C CI utils will no more provide a tool to do a check of the project, this is replaced by pre-commit,
a base configuration is provided in the example project.
Pull request checks
A workflow is provided to run the checks on the pull requests, it will run the c2cciutils-pr-checks command.
- Check that the commit message and the pull request title start with a capital letter.
- Check that there aren't any spelling issue in the commit message and in the pull request title.
- Add a message to the pull request with a link to the JIRA issue if the pull request branch name starts with
[a-zA-Z]+-[0-9]+-or end with-[a-zA-Z]+-[0-9]+.
Dependencies
In the example project there is a basic Renovate configuration, it will update the dependencies of the project. There is also a workflow to add a review on the Renovate pull requests to make the auto merge working on repository that required a review.
Backports
A workflow is provided to backport the pull requests on the stabilization branches, it will be triggered by
adding a label named backport <destination_branch> on the pull request.
Old workflows
GitHub will retain all the old workflows, so we need to delete them, the delete-old-workflows-run
workflow will delete the workflows older than 500 days.
Workflows
C2cciutils make easier to have those workflows in a project:
auto-review.yaml: Auto review the Renovate pull requestsbackport.yaml: Trigger the backports (work with labels)clean.yaml: Clean the Docker images related on a deleted feature branchmain.yaml: Main workflow especially with the c2cciutils-checks command
All the provided commands used in the workflow:
c2cciutils: some generic tools.c2cciutils-version: Create a new version of the project.c2cciutils-env: Print some environment information.c2cciutils-publish: Publish the project.c2cciutils-clean: Delete Docker images on Docker Hub after corresponding branch have been deleted.
Utilities
The following utilities are provided:
c2cciutils: some generic tools.c2cciutils-download-applications: Download the applications with version managed by Renovate, see below.c2cciutils-docker-logs: Display the logs of the application in Docker (compose).c2cciutils-k8s-install: Install a k3d / k3s cluster, see below.c2cciutils-k8s-logs: Display the logs of the application in the k8s cluster, see below.c2cciutils-k8s-db: Create a database in the k8s cluster, see below.c2cciutils-k8s-wait: Wait that the application started correctly in the cluster, see below.c2cciutils-docker-versions-gen: Generate the Docker package versions file (ci/dpkg-versions.yaml), see below.c2cciutils-pin-pipenv: Display all the dependencies that's in thePipenv.lockbut not in thePipenvto be able to pin them.c2cciutils-trigger-image-update: Trigger the ArgoCD repository about image update on the CI (automatically done in the publishing).c2cciutils-google-calendar: Tool to test the Google credentials for calendar API and refresh them if needed. Seec2cciutils-google-calendar -hfor more information.
New project
The content of example-project can be a good base for a new project.
New version
Requirements: the right version (>= 1.6) of c2cciutils should be installed with the version extra.
To create a new minor version you just should run c2cciutils-version --version=<version>.
You are welcome to run c2cciutils-version --help to see what's it's done.
Note that it didn't create a tag, you should do it manually.
To create a patch version you should just create tag.
Secrets
In the CI we need to have the following secrets::
HAS_SECRETSto be set to 'HAS_SECRETS', to avoid error errors from external pull requests, already set globally on Camptocamp organization.GOPASS_CI_GITHUB_TOKENandCI_GPG_PRIVATE_KEYrequired to initialize the gopass password store, the secrets exists in the Camptocamp organization but not shared on all project, then you should add your project to the shared list.
Use locally, in the projects that use c2cciutils
Install it: python3 -m pip install --user --requirement ci/requirements.txt
Dry run publish: GITHUB_REF=... c2cciutils-publish --dry-run ...
Configuration
You can get the current configuration with c2cciutils --get-config, the default configuration depends on your project.
Note that it didn't contain the default defined the schema and visible in the generated documentation.
You can override the configuration with the file ci/config.yaml.
At the base of the configuration you have:
version: Contains some regular expressions to find the versions branches and tags, and to convert them into application versions.publish: The publishing configuration, seec2cciutils/publish.pyfor more information.
Many actions can be disabled by setting the corresponding configuration part to False.
SECURITY.md
The SECURITY.md file should contain the security policy of the repository, especially the end of
support dates.
For compatibility with c2cciutils it should contain an array with at least the columns
Version and Supported Until. The Version column will contain the concerned version.
The Supported Until will contain the date of end of support dd/mm/yyyy.
It can also contain the following sentences:
Unsupported: no longer supported => no audit, no rebuild.Best effort: the support is ended, it is still rebuilt and audited, but this can be stopped without any notice.To be defined: not yet released or the date will be set related of another project release date (like for GeoMapFish).
See also GitHub Documentation
IDE
The IDE should be configured as:
- using
blackandisortwithout any arguments, - using the
editorconfigconfiguration.
VScode
- Recommend extensions to work well with c2cciutils:
- Prettier And use EditorConfig
- shell-format With the configuration
"shellformat.flag": "-bn". - Better TOML
- Other recommend extensions:
Select a formatter:
CTRL+MAJ+P- Format document With...
- Configure Default Formatter...
- Select the formatter
Publishing
To pypi
The config is like this:
versions:
# List of kinds of versions you want to publish, that can be:
# rebuild (specified with --type),
# version_tag, version_branch, feature_branch, feature_tag (for pull request)
It we have a setup.py file, we will be in legacy mode:
When publishing, the version computed from arguments or GITHUB_REF is put in environment variable VERSION, thus you should use it in setup.py, example:
VERSION = os.environ.get("VERSION", "1.0.0")
Also we consider that we use poetry with poetry-dynamic-versioning to manage the version, and poetry-plugin-tweak-dependencies-version to manage the dependencies versions.
Example of configuration:
[tool.poetry-dynamic-versioning]
enable = true
vcs = "git"
pattern = "^(?P<base>\\d+(\\.\\d+)*)"
format-jinja = """
{%- if env.get("VERSION_TYPE") == "version_branch" -%}
{{serialize_pep440(bump_version(base, 1 if env.get("IS_MASTER") == "TRUE" else 2), dev=distance)}}
{%- elif distance == 0 -%}
{{serialize_pep440(base)}}
{%- else -%}
{{serialize_pep440(bump_version(base), dev=distance)}}
{%- endif -%}
"""
Note that we can access to the environment variables VERSION,VERSION_TYPE and IS_MASTER.
Then by default:
- Tag with
1.2.3=> release1.2.3 - Commit on feature branch just do a validation
- Commit on
masterbranch after the tag 1.3.0 => release1.4.0.dev1 - Commit on
1.3branch after the tag 1.3.0 => release1.3.1.dev1
Authentication
If the file ~/.pypirc exists we consider that we ar already logged in also
we will do the login with the pypi server with OpenID Connect (OIDC).
The OIDC login is recommended because it didn't needs any additional secrets, but it need some configuration on pypi in the package, see the GitHub Documentation.
Integration if the package directly in a Docker image
To make it working in the Dockerfile you should have in the poetry stage:
ENV POETRY_DYNAMIC_VERSIONING_BYPASS=dev
RUN poetry export --extras=checks --extras=publish --output=requirements.txt \
&& poetry export --with=dev --output=requirements-dev.txt
And in the run stage
ARG VERSION=dev
RUN --mount=type=cache,target=/root/.cache \
POETRY_DYNAMIC_VERSIONING_BYPASS=${VERSION} python3 -m pip install --disable-pip-version-check --no-deps --editable=.
And in the Makefile:
VERSION = $(strip $(shell poetry version --short))
.PHONY: build
build: ## Build the Docker images
docker build --build-arg=VERSION=$(VERSION) --tag=$(GITHUB_REPOSITORY) .
To Docker registry
The config is like this:
latest: True
images:
- # The base name of the image we want to publish
name:
repository:
<internal_name>:
# The fqdn name of the server if not Docker hub
server:
# List of kinds of versions you want to publish, that can be: rebuild (specified using --type),
# version_tag, version_branch, feature_branch, feature_tag (for pull request)
version:
# List of tags we want to publish interpreted with `format(version=version)`
# e.g. if you use `{version}-lite` when you publish the version `1.2.3` the source tag
# (that should be built by the application build) is `latest-lite`, and it will be published
# with the tag `1.2.3-lite`.
tags:
# If your images are published by different jobs you can separate them in different groups
# and publish them with `c2cciutils-publish --group=<group>`
group:
By default, the last line of the SECURITY.md file will be published (docker) with the tag
latest. Set latest to False to disable it.
With the c2cciutils-clean the images on Docker hub for feature_branch will be removed on branch removing.
Download applications
In case some executables or applications from GitHub releases or any other URLs are required on the CI host and are not handled by any dependency manager, we provide a set of tools to install them and manage upgrades through Renovate.
Create an application file (e.-g. applications.yaml) with:
# yaml-language-server: $schema=https://raw.githubusercontent.com/camptocamp/c2cciutils/master/c2cciutils/schema-applications.json
# Application from GitHub release
<organization>/<project>:
get-file-name: <file name present in the release>
to-file-name: <The file name you want to create in ~/.local/bin>
finish-command: # The command you want to run after the file is downloaded
- - chmod # To be executable (usually required)
- +x
- <to-file-name>
- - <to-file-name> # Print the version of the application
- --version
# Application from GitHub release in a tar file (or tar.gz)
<organization>/<project>:
get-file-name: <file name present in the release>
type: tar
tar-file-name: <The file name available in the tar file>
to-file-name: <The file name you want to create in ~/.local/bin>
finish-command: [...] # The command you want to run after the file is downloaded
# Application from an URL
<application reference name>:
url-pattern: <The URL used to download the application>
to-file-name: <The file name you want to create in ~/.local/bin>
finish-command: [...] # The command you want to run after the file is downloaded
In the attributes url-pattern, get-file-name you can use the following variables:
{version}: The version of the application present in the version file.{version_quote}: The URL encoded version.{short_version}: The version without thevprefix.
The applications-versions.yaml file is a map of applications and their versions.
Add in your Renovate configuration:
regexManagers: [
{
fileMatch: ['^applications-versions.yaml$'],
matchStrings: [
'(?<depName>[^\\s]+): (?<currentValue>[^\\s]+) # (?<datasource>[^\\s]+)',
],
},
],
Now you need to call c2cciutils-download-applications --applications-file=applications.yaml --versions-file=applications-version.yaml
to install required applications on CI host before using them (an already installed application is installed only if needed).
Use Renovate to trigger a new build instead of the legacy rebuild
Run the command c2cciutils-docker-versions-gen camptocamp/image[:tag] to generate a file that is a kind of package lock of the Debian packages in the file ci/dpkg-versions.yaml.
Add in your renovate configuration:
regexManagers: [
{
fileMatch: ['^ci/dpkg-versions.yaml$'],
matchStrings: [" *(?<depName>[^'\\s]+): '?(?<currentValue>[^'\\s/]*[0-9][^'\\s/]*)'?"],
datasourceTemplate: 'repology',
versioningTemplate: 'loose',
},
],
When a new version of a Debian package will be available:
- Renovate will automatically open a pull request to update the file
ci/dpkg-versions.yaml. - And the continuous integration will build a new fresh Docker image with latest versions of all Debian packages.
Kubernetes
C2cciutils provide some commands for Kubernetes.
You can define a workflow like that:
- name: Install k3s/k3d (Kubernetes cluster)
run: c2cciutils-k8s-install
- name: Create a database to do the tests
run: c2cciutils-k8s-db --script=<my_script>.sql
- name: Install the application in the Kubernetes cluster
run: kubectl apply -f <my_application>.yaml
- name: Wait that the application is ready
run: c2cciutils-k8s-wait
- name: Print the application status and logs
run: c2cciutils-k8s-logs
if: always()
- name: Uninstall the application
run: kubectl delete -f <my_application>.yaml || true
- name: Cleanup the database
run: c2cciutils-k8s-db --cleanup
c2cciutils-k8s-install can be configured in the ci/config.yaml file, in section k8s/k3d/install-commands, default is:
- - k3d
cluster
create
test-cluster
--no-lb
--no-rollback
See also: K3d cluster create documentation.
c2cciutils-k8s-db can be configured in the ci/config.yaml file, in section k8s/db/chart-options, default is:
persistence.enabled: 'false'
tls.enabled: 'true'
tls.autoGenerated: 'true'
postgresqlPassword: mySuperTestingPassword
volumePermissions.enabled: 'true'
