Metrics deployment instructions

Create app

dokku$ dokku apps:create metrics
dokku$ dokku git:set metrics deploy-branch main

Configure app

dokku config:set metrics GITHUB_EBMDATALAB_TOKEN='xxx'
dokku config:set metrics GITHUB_OS_CORE_TOKEN='xxx'
dokku config:set metrics GITHUB_OS_TOKEN='xxx'
dokku config:set metrics SLACK_SIGNING_SECRET='xxx'
dokku config:set metrics SLACK_TECH_SUPPORT_CHANNEL_ID='xxx'
dokku config:set metrics SLACK_TOKEN='xxx'
dokku config:set metrics TIMESCALEDB_URL='xxx'
dokku config:set metrics SENTRY_DSN='xxx'

The GITHUB_EBMDATALAB_TOKEN and GITHUB_OS_CORE_TOKEN are fine-grained GitHub personal access tokens that are used for authenticating with the GitHub GraphQL API. Each token is assigned to a single organisation and should have the following read-only permissions:

  • organisation permissions: members
  • all repositories owned by the organisation with the following permissions: Code scanning alerts, Dependabot alerts, Issues, Metadata, Pull requests and Repository security advisories

The GITHUB_OS_TOKEN is a fine-grained GitHub personal access token that is used for authenticating with the GitHub REST API. It is assigned to a single organisation and should have the following read-only permissions:

  • organisation permissions: organisation codespaces
  • all repositories owned by the organisation with the following permissions: Codespaces and Metadata

Disable checks

Dokku performs health checks on apps during deploy by sending requests to port 80. This tool isn't a web app so it can't accept requests on a port. Disable the checks so deploys can happen.

dokku$ dokku checks:disable metrics

Set up storage

This is only needed for backfills which make use of a SQLite db cache.

# the metrics container runs as uid 1000 (metrics) internally, which corresponds to a dev user on the dokku3 host.
# the other dokku containers on dokku3 run as uid 1013 (dokku), which corresponds correctly to the dokku user on the dokku3 host.
# let's tell the container to run as 1013, then we can use the same file permissions
dokku$ dokku docker-options:add grafana deploy "--user 1013"
dokku$ dokku docker-options:add grafana run "--user 1013"

dokku$ dokku storage:ensure-directory metrics
dokku$ sudo chown -R dokku:dokku /var/lib/dokku/data/storage/metrics/
dokku$ dokku storage:mount metrics /var/lib/dokku/data/storage/metrics/:/storage

Ensure persistent logs

dokku$ sudo mkdir -p /var/log/journal
