Runs a Docker daemon to use containers for application deployment.


All service users can interact with Docker using the docker command.


The Flying Circus network is designed to allow customer application components to talk to each other securely and reliably. We recommend using the bridged networking option.

Programs running in a bridged container can access the rest of the network similar to programs run directly on the host. They can access neighbouring srv services in the same resource group and talk to the internet either directly through the frontend network or masqueraded through the server-to-server network.


We used to recommend the host networking option as a workaround due to incompatibilities with the NixOS firewall management. This option is now no longer recommended as it breaks fundamental assumptions about how containers work and how they are isolated.
