# Introduction
|
||
|
||
This is a [Helm](https://helm.sh/) chart for installing Mastodon into a
|
||
Kubernetes cluster. The basic usage is:
|
||
|
||
1. edit `values.yaml` or create a separate yaml file for custom values
|
||
1. `helm dep update`
|
||
1. `helm install --namespace mastodon --create-namespace my-mastodon ./ -f path/to/additional/values.yaml`
|
||
|
||
This chart has been tested on Helm 3.0.1 and above.
|
||
|
||
# Configuration
|
||
|
||
The variables that _must_ be configured are:
|
||
|
||
- password and keys in the `mastodon.secrets`, `postgresql`, and `redis` groups; if
|
||
left blank, some of those values will be autogenerated, but will not persist
|
||
across upgrades.
|
||
|
||
- SMTP settings for your mailer in the `mastodon.smtp` group.
|
||
|
||
# Administration
|
||
|
||
You can run [admin CLI](https://docs.joinmastodon.org/admin/tootctl/) commands in the web deployment.
|
||
|
||
```bash
|
||
kubectl -n mastodon exec -it deployment/mastodon-web -- bash
|
||
tootctl accounts modify admin --reset-password
|
||
```
|
||
|
||
or
|
||
```bash
|
||
kubectl -n mastodon exec -it deployment/mastodon-web -- tootctl accounts modify admin --reset-password
|
||
```
|
||
|
||
# Missing features
|
||
|
||
Currently this chart does _not_ support:
|
||
|
||
- Hidden services
|
||
- Swift
|
||
|
||
# Upgrading
|
||
|
||
Because database migrations are managed as a Job separate from the Rails and
|
||
Sidekiq deployments, it’s possible they will occur in the wrong order. After
|
||
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``` |
