Mattermost

Mattermost is an open source, private cloud, Slack-alternative from https://mattermost.com. It is used for enterprise collaboration/chat within P1 and for Big Bang.

This repo provides an implementation of Mattermost for Big Bang. Installation requires that the Mattermost Operator be installed in your cluster as a prerequisite.

Several of the important values to take note of when installing include:

• istio.enabled: This will enable istio networking for Mattermost within your cluster.
• users: This changes the maximum users for your instance, allowable values are 100, 1000, 5000, 10000, 25000 (NOTE: this may be limited on whether you have an enterprise license).
• replicaCount: The desired number of replicas for your instance. Defaults to 3 with the chart/values.yaml.
• enterprise.enabled: Enable enterprise features (if you don't also specify a license this only affects monitoring).
• enterprise.license: Value to add your license (entire license file contents - format shown in values). You can also manually add your license via the system console in Mattermost.
• minio.install: Install a minio instance standalone for Mattermost, for production you should specify a fileStore url, secret, and bucket.
• postgresql.install: Install a postgres instance standalone for Mattermost, for production you should specify a database secret
• sso.enabled: Enable SSO integration w/ Keycloak, requires additional config/values to point to your Keycloak.
• monitoring.enabled: Enabled Prometheus monitoring integration with Mattermost, this will only work if you toggle enterprise.enabled to true as well.
