DOCKER RUN IMAGE ID RETURNS NOTHING WINDOWS
On windows you can run: docker run -name=my_container -d -v %cd%/tmp:/var/log/nginx -p 8080:80 nginx Stop running containers On Linux and macOS, you can share a local temporary folder with a container by: docker run -name=my_container -d -v $(pwd)/tmp:/var/log/nginx -p 8080:80 nginx You can do it by running a container and using the -v option. Sometimes it is useful to sync files between the container and the local filesystem. Therefore, you can also try to launch a basic shell: docker exec -it my_container sh List running containersĪfter you’ve started a container, you can see all running containers executing: docker psīy appending -a, exited containers will also be listed: docker ps -a Share a local folder with a container Instead of the container name, you can also use the returned container ID for all following operations. Now you can execute a shell in the container and attach your input and output to it by using the options -i and -t: docker exec -it my_container bash You will get an error if this is not the case.įirst, start the container detached and give it a name: docker run -d -name my_container nginx This is only possible if the container has a shell installed. Sometimes it is helpful to log into a container. By using the -p 8080:80, the local port 8080 is forwarded to the container port 80. This NGINX container exposes a webserver on port 80. You can forward ports by using the -p option to, for example, a page that is exposed from your container: docker run -p 8080:80 nginx Therefore, you won't be able do any communication with it, and no files are stored in your current directory. If the container is started in the background, then you receive the container ID.īy default, the container runs in isolation.
You can also run it in the background by adding the -d option: docker run -d mysql You can stop the execution by pressing CTRL+C. If the image does not exist, then it will be downloaded. Start a Docker ImageĪn image can be started in the foreground by: docker run cassandra The option -f forces the execution, because otherwise you would get an error if the image is referenced by more than 1 tag. To remove the image directly, it is easier to delete the image by image id: docker image rm 3a5e53f63281 -f Therefore, to remove it completely, I need to also remove another version tag: docker rm mysql:8.0.19 In my case, the image is still tagged with mysql:8.0.19. Therefore, there is a handy option to filter certain information: docker inspect -format='' 3a5e53f63281 Remove Docker ImagesĪ single image can be removed by: docker rm mysql:latest Alternatively, you can also use the image ID to get the information: docker inspect 3a5e53f63281 To get more information about an image, you can inspect it: docker inspect mysql:latest MySQL, version 8.0.19, one tagged as latest version.Here are the most important commands to use Docker in your daily business efficiently. You can start complex applications quickly, develop in isolation, and still have a very good performance. Docker has been widely adopted and is a great vehicle to deploy an application to the cloud (or some other Docker-ready infrastructure).
