Upgrading the Comet ML Helm Chart¶

Normal Upgrade Steps¶

helm upgrade <release-name> . -f override-values.yaml

From <=4.0.x to >=4.1.x¶

Chart Name changed to 'comet-ml', so update repository pull accordingly.

Due to a change in label selectors, it is not possible to execute a helm upgrade, instead it is necessary to uninstall and reinstall the chart.

Internal Redis¶

A change in how the Internal Redis is installed requires moving some non-default configurations. The following shows to where certain custom settings have been moved.

# Prior to 4.1.0
redis:
  enableInternalRedis: true
  image:
    repoistory: docker.io/redis
    tag: 5.0.7
  mpm:
    redisHost: "redis-internal"
    redisPort: "6379"
    redisToken: "NA"
    backupPath: "/opt/comet-ml/backups/redis/regular"
    maxTotalWorkers: "60"
    maxWaitTimeMs: "5000"
    redisSsl: false
    readTimeoutMs: "2000"
  persistenceVolume:
    storageClassName: "comet-generic"
    redisInternalVolumeSize: "10Gi"
  service:
    type: ClusterIP
    port: 6379
  nodeSelector: {}
  tolerations: []
  affinity: {}

Becomes:

# From 4.1.0
backend:
  mpm:
    # …
    redis:
      backupPath: "/opt/comet-ml/backups/redis/regular"
      maxTotalWorkers: "60"
      maxWaitTimeMs: "5000"
      readTimeoutMs: "2000"
# …
redis:
  enableInternalRedis: true
  redisHost: "redis-internal"
  redisPort: "6379"
  redisToken: "NA"
  redisSSL: false
redisInternal:
  image:
    registry: docker.io
    repoistory: redis
    tag: 5.0.7
  master:
    service:
      type: ClusterIP
      ports:
        redis: 6379
    persistence:
      enabled: true
      storageClass: "comet-generic"
      size: 10Gi
    nodeSelector: {}
    tolerations: []
    affinity: {}

Be sure to compare your override values to the defaults in values.yaml or those emitted from helm show values comet-ml/comet-ml as it is not necessary to override values when not deviating from the default.
