Important environment variables

The datalust/seq container can be configured using the following environment variables, passed on the Docker command line as -e NAME=VALUE:

Name	Description	Example value	Default value
`ACCEPT_EULA`	Set to `Y` to indicate acceptance of the Seq End User License Agreement	`Y`	`N`
`SEQ_API_CANONICALURI`	The base URI that Seq will use when generating links back to the Seq server (optional; generally required for OIDC login, alert notifications, and Kubernetes ingress support)	`https://seq.example.com/`

Setting an initial administrator username and password

A default password for the admin account can be passed through the SEQ_FIRSTRUN_ADMINPASSWORD environment variable, or using the --default-admin-password-stdin argument.

The admin account's username can be overridden with the SEQ_FIRSTRUN_ADMINUSERNAME environment variable.

The default when no password is supplied is to not enable authentication.

📘
This step can only be performed the very first time the container is started. Setting SEQ_FIRSTRUN_* after this will have no effect.

Full list of supported options

The datalust/seq container supports the full range of options documented in the Server Configuration reference.

Options can be specified using the SEQ_* family of environment variables, the config set and secret set commands, or recorded directly in Seq.json under the mounted data volume.
