Use the Reis CLI to manage .env-style files using command-line flags. Env files are key=value pairs (one per line) that get mounted into a container at a path of your choosing.

Create an env file

reis env_file:create \
  --org <organisation-id> \
  --name "App Env" \
  --handle app-env \
  --content_file ./config/app.env

List env files

reis env_file:list --org <organisation-id>

Show an env file

reis env_file:show <env-file-id> --org <organisation-id>

Rotate (update content)

reis env_file:rotate <env-file-id> \
  --org <organisation-id> \
  --content_file ./config/app-v2.env

List versions

reis env_file:versions <env-file-id> --org <organisation-id>

Activate a previous version

reis env_file:activate <env-file-id> <version-number> --org <organisation-id>

Note: env files use env_file:activate (without the _version suffix). The other config types use *:activate_version.

Delete an env file

reis env_file:delete <env-file-id> --org <organisation-id>

Add --force to skip the confirmation prompt.

Required flags for create

Flag	Description
`--name`	Human-readable display name
`--handle`	DNS-1123-compliant identifier (auto-generated from name if omitted)
`--content_file`	Path to a file containing `KEY=value` lines

Attach to a project

reis project:attach <project-id> env_files app-env

Singular alias env_file is also accepted. The project-id is the UUID Reis returns from project:list or project:show.

Detach from a project

reis project:detach <project-id> env_files app-env

If a running container still mounts the env file, detach is rejected with a 409 naming the blocking container — tear it down (or remove its env_files block) and retry.
