_A K8S based solution to build and operate Geospatial Platforms_
> [!CAUTION]
> The [Dowker swarm](https://docs.docker.com/engine/swarm/) version is no more supported.
The latest available version supporting **Docker Swarm** is the [v0.18.0](https://github.com/kalisio/kargo/releases/tag/v0.18.0).
## Helm charts management
The chart management scripts (`release-dev-chart.sh` and `release-chart.sh`) both require :
* a valid `rclone` configuration, ie. containing a remote/alias named `kalisio_charts` pointing on the object storage bucket path where we backup our charts.
* an `helm` command able to push on our OCI-based registry, ie. you need to use `helm registry login harbor.portal.kalisio.com/kalisio` and enter the required credentials.
### HOWTO generate chart dev versions
Use the `./scripts/release-dev-chart.sh`. It takes a single parameter, the chart to release. If no parameter is given, it'll release _all_ charts.
The script will package the requested chart(s) then push on our OCI registry and on a backup s3 storage.
### HOWTO make a chart release
1. Prepare the new chart version, update chart version in $CHART/Chart.yaml
2. Push your changes to the central repository
3. Use `./scripts/release-chart.sh $CHART` where $CHART is the name of the chart to release (mapserver, kano, ...)
The script will package the chart, push on our oci registry and on a backup s3 storage. If everything is ok, it'll make a git tag named `$CHART-$VERSION`
## Docker images management
* kargo specific container images (tileservergl & friends ...)
* use a commit message including `[build app-name tag]`
## Best practices
### Docker images
* Prefer `-slim` images as base and use multi stage builds to reduce image sizes
* Make your docker image run as unpriviliged user
* If it's node based, and using a node image as base, there's a 'node' user (uid 1000) already available
* Copy app's files using COPY --chown node
* Make your command run as 'node' user
* If there's no preinstalled user, create one and use it
* Since it'll run as unpriviliged user, if you need to open ports, make sure they're >= 1024
* Snippet to install packages with apt and clean afterwards:
```
RUN \
DEBIAN_FRONTEND=noninteractive && \
apt-get update && \
apt-get --no-install-recommends --yes install \
openjdk-11-jre-headless \
ca-certificates \
gdal-bin && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*
```
* Snippet to install dependencies with yarn and clean afterwards
```
RUN \
yarn global add @weacast/grib2json@${GRIB2JSON_TAG} && \
chmod a+x /usr/local/share/.config/yarn/global/node_modules/@weacast/grib2json/bin/grib2json && \
yarn cache clean
```
### Helm charts
* Define appVersion to the docker image tag it's supposed to pull (no latest in defined charts, latest can be specified using values.yaml in infra definition)
* Include configurable resource requests & limits
* Include configurable security context and put sensible defaults in chart's values.yaml
* If it's being deployed on some preprod infra, then chart version should be at least 1.0.0
