Sentry 10 helm charts

Sentry is a cross-platform crash reporting and aggregation platform.

This repository aims to support Sentry 10 and move out from the deprecated Helm charts official repo.

Big thanks to the maintainers of the deprecated chart. This work has been partly inspired by it.

How this chart works

helm repo add sentry https://sentry-kubernetes.github.io/charts

Values

For now the full list of values is not documented but you can get inspired by the values.yaml specific to each directory.

Upgrading from 14.x.x version of this Chart to 15.x.x

Chart dependencies has been upgraded because of bitnami charts removal. Changes:

• nginx.service.port: 80 > nginx.service.ports.http: 80
• kafka.service.port > kafka.service.ports.client

Bumped dependencies:

• redis > 16.12.1 - latest version of chart

• nginx > 12.0.4 - latest version of chart

Upgrading from 13.x.x version of this Chart to 14.0.0

ClickHouse was reconfigured with sharding and replication in-mind, If you are using external ClickHouse, you don't need to do anything.

WARNING: You will lose current event data
Otherwise, you should delete the old ClickHouse volumes in-order to upgrade to this version.

Upgrading from 12.x.x version of this Chart to 13.0.0

The service annotions have been moved from the service section to the respective service's service sub-section. So what was:

service:
  annotations:
    alb.ingress.kubernetes.io/healthcheck-path: /_health/
    alb.ingress.kubernetes.io/healthcheck-port: traffic-port

will now be set per service:

sentry:
  web:
    service:
      annotations:
        alb.ingress.kubernetes.io/healthcheck-path: /_health/
        alb.ingress.kubernetes.io/healthcheck-port: traffic-port

relay:
  service:
    annotations:
      alb.ingress.kubernetes.io/healthcheck-path: /api/relay/healthcheck/ready/
      alb.ingress.kubernetes.io/healthcheck-port: traffic-port

Upgrading from 10.x.x version of this Chart to 11.0.0

If you were using clickhouse tabix externally, we disabled it per default.

Upgrading from 9.x.x version of this Chart to 10.0.0

If you were using clickhouse ImagePullSecrets, we unified the way it's used.

Upgrading from 8.x.x version of this Chart to 9.0.0

to simplify 1st time installations, backup value on clickhouse has been changed to false.

clickhouse.clickhouse.configmap.remote_servers.replica.backup

Upgrading from 7.x.x version of this Chart to 8.0.0

• the default value of features.orgSubdomains is now "false"

Upgrading from 6.x.x version of this Chart to 7.0.0

• the default mode of relay is now "proxy". You can change it through the values.yaml file
• we removed the githubSso variable for the oauth github configuration. It was using the old environment variable, that doesn't work with Sentry anymore. Just use the common github.xxxx configuration for both oauth & the application integration.

Upgrading from 5.x.x version of this Chart to 6.0.0

• The sentry.configYml value is now in a real yaml format
• If you were previously using relay.asHook, the value is now asHook

Upgrading from 4.x.x version of this Chart to 5.0.0

As Relay is now part of this chart your need to make sure you enable either Nginx or the Ingress. Please read the next paragraph for more informations.

If you are using an ingress gateway (like istio), you have to change your inbound path from sentry-web to nginx.

NGINX and/or Ingress

By default, NGINX is enabled to allow sending the incoming requests to Sentry Relay or the Django backend depending on the path. When Sentry is meant to be exposed outside of the Kubernetes cluster, it is recommended to disable NGINX and let the Ingress do the same. It's recommended to go with the go to Ingress Controller, NGINX Ingress but others should work as well.

Note: if you are using NGINX Ingress, please set this annotation on your ingress : nginx.ingress.kubernetes.io/use-regex: "true". If you are using additionalHostNames the nginx.ingress.kubernetes.io/upstream-vhost annotation might also come in handy. It sets the Host header to the value you provide to avoid CSRF issues.

Clickhouse warning

Snuba only supports a UTC timezone for Clickhouse. Please keep the initial value!

Upgrading from 3.1.0 version of this Chart to 4.0.0

Following Helm Chart best practices the new version introduces some breaking changes, all configuration for external resources moved to separate config branches: externalClickhouse, externalKafka, externalRedis, externalPostgresql.

Here is a mapping table of old values and new values:

Before	After
postgresql.postgresqlHost	externalPostgresql.host
postgresql.postgresqlPort	externalPostgresql.port
postgresql.postgresqlUsername	externalPostgresql.username
postgresql.postgresqlPassword	externalPostgresql.password
postgresql.postgresqlDatabase	externalPostgresql.database
postgresql.postgresSslMode	externalPostgresql.sslMode
redis.host	externalRedis.host
redis.port	externalRedis.port
redis.password	externalRedis.password

Upgrading from deprecated 9.0 -> 10.0 Chart

As this chart runs in helm 3 and also tries its best to follow on from the original Sentry chart. There are some steps that needs to be taken in order to correctly upgrade.

From the previous upgrade, make sure to get the following from your previous installation:

• Redis Password (If Redis auth was enabled)
• PostgreSQL Password Both should be in the secrets of your original 9.0 release. Make a note of both of these values.

Upgrade Steps

Due to an issue where transferring from Helm 2 to 3. Statefulsets that use the following: heritage: {{ .Release.Service }} in the metadata field will error out with a Forbidden error during the upgrade. The only workaround is to delete the existing statefulsets (Don't worry, PVC will be retained):

kubectl delete --all sts -n <Sentry Namespace>

Once the statefulsets are deleted. Next steps is to convert the helm release from version 2 to 3 using the helm 3 plugin:

helm3 2to3 convert <Sentry Release Name>

Finally, it's just a case of upgrading and ensuring the correct params are used:

If Redis auth enabled:

helm upgrade -n <Sentry namespace> <Sentry Release> . --set redis.usePassword=true --set redis.password=<Redis Password> --set postgresql.postgresqlPassword=<Postgresql Password>

If Redis auth is disabled:

helm upgrade -n <Sentry namespace> <Sentry Release> . --set postgresql.postgresqlPassword=<Postgresql Password>

Please also follow the steps for Major version 3 to 4 migration

PostgreSQL

By default, PostgreSQL is installed as part of the chart. To use an external PostgreSQL server set postgresql.enabled to false and then set postgresql.postgresHost and postgresql.postgresqlPassword. The other options (postgresql.postgresqlDatabase, postgresql.postgresqlUsername and postgresql.postgresqlPort) may also want changing from their default values.

To avoid issues when upgrade this chart, provide postgresql.postgresqlPassword for subsequent upgrades. This is due to an issue in the PostgreSQL chart where password will be overwritten with randomly generated passwords otherwise. See https://github.com/helm/charts/tree/master/stable/postgresql#upgrade for more detail.

Persistence

This chart is capable of mounting the sentry-data PV in the Sentry worker and cron pods. This feature is disabled by default, but is needed for some advanced features such as private sourcemaps.

You may enable mounting of the sentry-data PV across worker and cron pods by changing filestore.filesystem.persistence.persistentWorkers to true. If you plan on deploying Sentry containers across multiple nodes, you may need to change your PVC's access mode to ReadWriteMany and check that your PV supports mounting across multiple nodes.

Roadmap

• Lint in Pull requests
• Public availability through Github Pages
• Automatic deployment through Github Actions
• Symbolicator deployment
• Testing the chart in a production environment
• Improving the README
