To list all containers, run the following command (default shows just running). First, stop it from the foreground mode by pressing, then run it in a detached mode as shown: # docker run -d -rm -p 8000:80 -p 8443:443 -name pandorafms pandorafms/pandorafms:latest To run a Docker container in the background, use the use -d=true or just -d option. Which means you can not run any other commands while the container is running. The disadvantage of running a container in the foreground is that you can not access the command prompt anymore, as you can see from the screenshot above.

#Docker run image shell how to

This example shows how to start a Docker container in foreground mode: # docker run -rm -ti -p 8000:80 -p 8443:443 -name pandorafms pandorafms/pandorafms:latest Importantly, the -rm option tells Docker to automatically remove the container when it exits. You can also attach it to one or more file descriptors ( STDIN, STDOUT and/or STDERR) using the -a= flag. The :debug image set for each language provides a busybox shell to enter.There are also command line options to configure it more such as -t to allocate a pseudo-tty to the process, and -i to keep STDIN open even if not attached. Debug Imagesĭistroless images are minimal and lack shell access.

Jibįor full documentation on how to use Jib to generate Docker images from Maven and Gradle, see the GoogleContainerTools/jib repository. See here for more information on how these images are built and released.

See here for examples on how to complete some common tasks in your image: We have some examples on how to run some common application stacks in the /examples directory. package_managerĮxamples can be found in this repository in the examples directory. įor full documentation on how to use bazel to generate Docker images, see the bazelbuild/rules_docker repository.įor documentation and examples on how to use the bazel package manager rules, see. To run any example, go the the directory for the language and run docker build -t myapp.

If you'd like to learn more, please see the documentation on multi-stage builds. The basic idea is that you'll have one stage to build your application artifacts, and insert them into your runtime distroless image.

Note: This requires Docker 17.05 or higher. The following images are also published on gcr.io, but are considered experimental and not recommended for production usage: Pick the right base image for your application stack We publish the following distroless base images on gcr.io: That means the Dockerfile ENTRYPOINT command must be specified in vector form, to avoid the container runtime prefixing with a shell.īut this does not work: ENTRYPOINT 'myapp'ĭocker multi-stage builds make using distroless images easy. Note that distroless images by default do not contain a shell. These images are built using the bazel tool, but they can also be used through other Docker image build tooling. CVE) and reduces the burden of establishing provenance to just what you need. It improves the signal to noise of scanners (e.g. Restricting what's in your runtime container to precisely what's necessary for your app is a best practice employed by Google and other tech giants that have used containers in production for many years. They do not contain package managers, shells or any other programs you would expect to find in a standard Linux distribution.įor more information, see this talk ( video). 'Distroless' images contain only your application and its runtime dependencies.
