The host-dir can either be an absolute path or a name value. The container-dir must always be an absolute path such as /src/docs. This is consistent with the expected behavior of the mount command. Once the mount is removed, the content is accessible again. If the path /webapp already exists inside the container’s image, the /src/webapp mount overlays but does not remove the pre-existing content. This command mounts the host directory, /src/webapp, into the container at /webapp. $ docker run -d -P -name web -v /src/webapp:/webapp training/webapp python app.py In this example, though, the name is faster. To do this, you supply both the network name and the container name. You can remove a container from a network by disconnecting the container. You can then create a container from our new image. This limitation is set globally to encourage optimization of the overall size of images. Note: An image can’t have more than 127 layers regardless of the storage driver. When all the instructions have executed you’re left with the 97feabe5d2ed image (also helpfully tagged as ouruser/sinatra:v2) and all intermediate containers will get removed to clean things up. You can see that each step creates a new container, runs the instruction inside that container and then commits that change - just like the docker commit work flow you saw earlier.

Next you can see each instruction in the Dockerfile being executed step-by-step.

This is done because the Docker daemon does the actual build of the image and it needs the local context to do it. The first thing Docker does is upload the build context: basically the contents of the directory you’re building in. Now you can see the build process at work. Note: You can also specify a path to a Dockerfile. to indicate a Dockerfile in the current directory. You’ve also specified the location of our Dockerfile using the. You’ve specified our docker build command and used the -t flag to identify our new image as belonging to the user ouruser, the repository name sinatra and given it the tag v2.

A user image belongs to a member of the Docker community and is built and maintained by them. You’ve also seen user images, for example the training/sinatra image you’ve chosen. These can be identified by their single word names. These base images are provided by Docker Inc and are built, validated and supported. So far you’ve seen two types of images repositories, images like ubuntu, which are called base or root images. You’ve reviewed the images available to use and you decided to use the training/sinatra image. Automated repositories are Automated Builds that allow you to validate the source and content of an image. Official Repositories are a carefully curated set of Docker repositories supported by Docker, Inc.

You’ve received a list of image names, descriptions, Stars (which measure the social popularity of images - if a user likes an image then they can “star” it), and the Official and Automated build statuses. You can see the command returns a lot of images that use the term sinatra. Luisbebop/docker-sinatra-hello-world 0 īmorearty/handson-sinatra handson-ruby + Sinatra for Hands on with D.
