Fluxcloud is a tool to receive events from the Weave flux.
Weave Flux is a useful tool for managing the state of your Kubernetes cluster.
Fluxcloud is a valid upstream for Weave, allowing you to send Flux events to Slack or a webhook without using Weave Cloud.
Please see the Weave Flux setup documentation for setting up Flux.
To use Fluxcloud, you can deploy fluxcloud as either a sidecar to Flux or a seperate deployment.
To deploy as a sidecar, see examples/flux-deployment-sidecar.yaml.
To deploy independently, see examples/fluxcloud.yaml.
Set the following environment variables in your chosen deployment:
SLACK_URL: the Slack webhook URL to use.SLACK_USERNAME: the Slack username to use when sending messages.SLACK_CHANNEL: the Slack channel to send messages to.SLACK_ICON_EMOJI: the Slack emoji to use as the icon.GITHUB_URL: the URL to the Github repository that Flux uses, used for Slack links.WEBHOOK_URL: if the exporter is "webhook", then the URL to use for the webhook.EXPORTER_TYPE(optional): The type of exporter to use. (Choices: slack, webhook, Default: slack)
And then apply the configuration:
kubectl apply -f examples/fluxcloud.yaml
Set the --connect flag on Flux to --connect=ws://fluxcloud.
There are multiple exporters that you can use with fluxcloud. If there is not a suitable one already, feel free to contribute one by implementing the exporter interface!
The default exporter to use is Slack. To use the Slack exporter, set the SLACK_URL,
SLACK_USERNAME, and SLACK_CHANNEL environment variables to use. You can also
optionally set the EXPORTER_TYPE to "slack".
Events can be sent to an arbitrary webhook by setting the EXPORTER_TYPE to "webhook" and
then setting the WEBHOOK_URL to the URL to send the webhook to.
Fluxcloud will send a POST request to the provided URL with the encoded event as the payload.
Fluxcloud follows semver for versioning, but also publishes development images tagged
with $BRANCH-$COMMIT.
To track release images:
fluxctl policy -c kube-system:deployment/fluxcloud --tag-all='v0*'
To track the latest pre-release images:
fluxctl policy -c kube-system:deployment/fluxcloud --tag-all='master-*'
And then you can automate it:
fluxctl automate -c kube-system:deployment/fluxcloud
