Database Section

This section of the ESS installer GUI will only be present if you are using the Kubernetes deployment option or you have opted to use your own PostgreSQL for a Standalone deployment.

If you have not yet set up your PostgreSQL, you should ensure you have done so before proceeding, see the relevant PostgreSQL section from the Requirements and Recommendations page:

All settings configured via the UI in this section will be saved to your deployment.yml, with the contents of secrets being saved to secrets.yml. You will find specific config examples under each respective section.

Config Example
  • deployment.yml 
    spec:
  components:
    synapse:
      config:
        postgresql:
  • secrets.yml 
    apiVersion: v1
kind: Secret
metadata:
  name: synapse
  namespace: element-onprem
data:
  postgresPassword:

By default, if only complete the required settings on this page, the following will be added to your deployment.yml (see example below).

Config Example 
spec:
  components:
    synapse:
      config:
        postgresql:
          database: synapse
          host: db.example.com
          passwordSecretKey: postgresPassword
          user: test-username

Host

Config Example 
spec:
  components:
    synapse:
      config:
        postgresql:
          host: db.example.com

Port

Config Example 
spec:
  components:
    synapse:
      config:
        postgresql:
          # port not present when left as default 5432
          port: 5432

Defaults to 5432, either keep if correct or provide the required port of the PostgreSQL Database you configured per the previously mentioned Requirements and Recommendations to use for Synapse.

SSL Mode

Config Example 
spec:
  components:
    synapse:
      config:
        postgresql:
          # sslMode not present when left as default `require` 
          sslMode: require

          # sslMode: prefer
          # sslMode: verify-ca
          # sslMode: verify-full
