When you are running your Docker containers, you can attach them to your current shell or run them as background tasks in your server. Detached mode means your shell is free, you can continue to type or run other things without affecting your Docker containers. Here we will run an nginx:alpine image in detached mode with -d option with the help of this command docker container run --name web -d -p 80:80 nginx:alpine
[root@server1 ~]# docker container run --name web -d -p 80:80 nginx:alpine Unable to find image 'nginx:alpine' locally alpine: Pulling from library/nginx 4167d3e14976: Pull complete bb292c78f105: Pull complete Digest: sha256:abe5ce652eb78d9c793df34453fddde12bb4d93d9fbf2c363d0992726e4d2cad Status: Downloaded newer image for nginx:alpine 81f14281fc5b1cf9ff970837f9a37722da5cb310111c47687963e14404a04862 [root@server1 ~]# [root@server1 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 81f14281fc5b nginx:alpine "nginx -g 'daemon of…" 9 seconds ago Up 7 seconds 0.0.0.0:80- >80/tcp web [root@server1 ~]# docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 81f14281fc5b nginx:alpine "nginx -g 'daemon of…" 4 minutes ago Up 4 minutes 0.0.0.0:80->80/tcp web [root@server1 ~]#
It is not detecting the image in the local repository cache of the Docker host where we are running this command. So it is pulling all the required layers from Docker Hub and running the container via using this image in detached mode.
And at the end, we are listing all running Docker containers with the help of docker ps command. The new syntax (recommended one) is docker container ls
Let us know if you could able to run your container in detached mode! Thanks.
