Docker images

Run a public image as it is, with no repository: a tool someone else publishes, or your own image from a registry.

Creating one

New project → Deploy a public Docker image, or:

Terminal

arrah projects create --image nginx:alpine --port 80 --deploy

Image: name:tag or registry/owner/name:tag
Registries: Docker Hub, ghcr.io, quay.io, gcr.io, public.ecr.aws, registry.gitlab.com, mcr.microsoft.com, registry.k8s.io
Port: The one you set, else the single port the image declares, else 8080.
Largest image: 4 GB

Public images only. There is no place for registry credentials yet.
It runs in the same sandbox as every application and gets the project's variables, database, Redis and storage like any project.
Deploy again to pull a newer image under the same tag. Rollback works as usual.
What the image writes to its own disk is lost on the next deployment. Keep data in a database, Redis or file storage — or add a permanent disk for the directory it writes to.
There is nothing to follow, so no automatic deploys, branch environments or pull request previews.
