The -rm option means to remove the container once it exits/stops. On Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.Ĭreate and start the container as a detached process. The host networking driver only works on Linux hosts, and is not supported Nginx listen on a different port, see the This procedure requires port 80 to be available on the Docker host. Process namespace, and user namespace, the nginx process is isolated from the However, in all other ways, such as storage, Same level of isolation as if the nginx process were running directly on theĭocker host and not in a container. From a networking point of view, this is the The goal of this tutorial is to start a nginx container which binds directly # Do not mount anything over /app or the code in the image.This series of tutorials deals with networking standalone containers which bindĭirectly to the Docker host’s network, with no network isolation. Source: app-data # when type: volume, this is a volume name # need to manipulate files on the host, and on MacOS/Windows # Use a named volume for opaque application data you do not # Use a bind mount to read back log files you need to read them # Use a bind mount to inject configuration files you need to I would not automatically reach for a named volume because the Docker documentation suggests it's preferred. Since you can't access the contents of a named volume from outside of Docker, they're harder to back up and manage, and a poor match for tasks like injecting config files and reviewing logs. IMHO the Docker documentation is very enthusiastic about named volumes and glosses over their downsides. volumes:Īccording to the docs, "volumes are preferred." Since you're mounting a host directory, you need to specify type: bind in the extended syntax. The type: field says whether it's a named volume, a bind mount, or a couple of other things. Do I have to use the short syntax for that? So, I much prefer having volumes instead of binds. While bind mounts are dependent on theĭirectory structure and OS of the host machine, volumes are completely Volumes are the preferred mechanism for persisting data generated byĪnd used by Docker containers. Does this make sense, different features according to syntax?įurthermore, again, according to the docs, So, it seems that in the long syntax I have to use the bind type to mount a host path. Or the name of a volume defined in the top-level volumes key. Source: the source of the mount, a path on the host for a bind mount, However, if I try to use the long syntax, that doesn't work anymore. When configuring a docker-compose.yml, I can easily mount a volume that maps a folder from the host machine to the container.
