Channel Tag | Currently | Architectures | ||

Channel Tag shows the most stable channel for that track. A track is a combination of both the application version and the underlying Ubuntu series, eg 1.0-22.04
.
Channels are ordered from the most stable to the least stable
, candidate
, beta
, edge
.
More risky channels are always implicitly available.
So if beta
is listed, you can also pull edge
. If candidate
is listed, you can pull beta
and edge
.
When stable
is listed, all four are available.
Images are guaranteed to progress through the sequence edge
, beta
, candidate
before stable
.
If your usage includes commercial redistribution or requires unavailable channels/versions, please get in touch with the Canonical team (or using rocks@canonical.com).
Launch this image locally:
docker run -d --name cortex-container -e TZ=UTC -p 32709:9009 ubuntu/cortex:1.11-22.04_beta
Access your Cortex server at http://localhost:32709
.
Parameters
Parameter | Description |
---|---|
-e TZ=UTC | Timezone. |
-p 32709:9009 | Expose Cortex on localhost:32709 . |
-v /my/local/cortex.yaml:/etc/cortex/cortex.yaml | Local configuration filecortex.yaml (try this example). |
Testing/Debugging
To debug the container:
docker logs -f cortex-container
To get an interactive shell:
docker exec -it cortex-container /bin/bash
Works with any Kubernetes; if you don't have one, we recommend you install MicroK8s and microk8s.enable dns storage
then snap alias microk8s.kubectl kubectl
.
Download
cortex.yaml and
cortex-deployment.yml and set containers.cortex.image
in cortex-deployment.yml
to your chosen channel tag (e.g. ubuntu/cortex:1.11-22.04_beta
), then:
kubectl create configmap cortex-config --from-file=main-config=cortex.yaml
kubectl apply -f cortex-deployment.yml
You will now be able to connect to the Cortex server on localhost:32709
.
