1. `docker push :tagname` - It pushed the image to the host mentioned.
1. `docker pull ` - To rename a image.
1. `docker login` - To loign to docker hub

1. -v "%cd%:/app" in windows ( For Bind mounds)
1. -v ${pwd}:app in mac/linux
1. `docker run -v /app/data` - Anonymous Voumes.Survives shutdown/stopping of containers but not removal. Can't be shared by container. Created by `--v` flag or by writting docker file.
1. `docker run -v data:/app/data` - Named Volumes. Created by `--v` flages. In general and not linked to particular container. also survive removals. Can be shared across containers.
1. `docker run -v /path/to/code:/app/code` - Bind Mount. Not tied to particular container. Can be shared across containers. survives restart and removal.`ro` can be added to tell docker that its a read only volume.
## Network
