upgrading Mastodon versions, it may sometimes be necessary to manually delete
the Rails and Sidekiq pods so that they are recreated against the latest
migration.
# Upgrades in 2.0.0
## Fixed labels
Because of the changes in [#19706](https://github.com/mastodon/mastodon/pull/19706) the upgrade may fail with the following error:
```Error: UPGRADE FAILED: cannot patch "mastodon-sidekiq"```
If you want an easy upgrade and you're comfortable with some downtime then
simply delete the -sidekiq, -web, and -streaming Deployments manually.
If you require a no-downtime upgrade then:
1. run `helm template` instead of `helm upgrade`
2. Copy the new -web and -streaming services into `services.yml`
3. Copy the new -web and -streaming deployments into `deployments.yml`
4. Append -temp to the name of each deployment in `deployments.yml`
5. `kubectl apply -f deployments.yml` then wait until all pods are ready
6. `kubectl apply -f services.yml`
7. Delete the old -sidekiq, -web, and -streaming deployments manually
8. `helm upgrade` like normal
9. `kubectl delete -f deployments.yml` to clear out the temporary deployments
## PostgreSQL passwords
If you've previously installed the chart and you're having problems with
postgres not accepting your password then make sure to set `username` to
`postgres` and `password` and `postgresPassword` to the same passwords.
```yaml
postgresql:
auth:
username: postgres
password: <same password>
postgresPassword: <same password>
```
And make sure to set `password` to the same value as `postgres-password`
in your `mastodon-postgresql` secret:
```kubectl edit secret mastodon-postgresql```
