portainer.io: MAKING DOCKER MANAGEMENT EASY. Build and manage your Docker environments with ease today.<\/a><\/p>\n\n\n\n <\/p>\n\n\n\n dive: About\nA tool for exploring each layer in a docker image<\/a><\/p>\n\n\n\n You can start a new container by using the run command and specify the desired image <\/p>\n\n\n\n As a result, you are in the container at the bash command line<\/p>\n\n\n\n Python<\/strong><\/p>\n\n\n\n Java<\/strong><\/p>\n\n\n\n Configuration is stored under<\/p>\n\n\n\n Alternative you can run<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\nUseful commands<\/h2>\n\n\n\n
Some useful flags include:\u00a0-a<\/code>\u00a0\/\u00a0-all<\/code>\u00a0for all containers (default shows just running) and\u00a0\u2014-quiet<\/code>\u00a0\/-q<\/code>\u00a0to list just their ids (useful for when you want to get all the containers).<\/li>pull<\/code>\u00a0and try without needing to define and configure your own. To download a particular image, or set of images (i.e., a repository), use\u00a0docker pull<\/code>.<\/li>
A build\u2019s context is the set of files located in the specified\u00a0PATH<\/code>\u00a0or\u00a0URL<\/code>. Use the\u00a0-t<\/code>\u00a0flag to label the image, for example\u00a0docker build -t my_container\u00a0.<\/code>\u00a0with the\u00a0.<\/code>\u00a0at the end signalling to build using the currently directory.<\/li>
You can follow this on with other commands, such as\u00a0-it bash<\/code>\u00a0to then run bash from within the container.\u00a0
Also see\u00a0<\/em>Top 10 options for docker run\u200a\u2014\u200aa quick reference guide for the CLI command<\/em><\/a>.\u00a0<\/em>docker run my_image -it bash<\/code><\/li>
You must specify a container and can use flags, such as\u00a0--follow<\/code>\u00a0to follow the output in the logs of using the program.\u00a0docker logs --follow my_container<\/code><\/li>
Volumes are the preferred mechanism for persisting data generated by and used by Docker containers.<\/li>docker rm my_container<\/code><\/li>docker rmi my_image<\/code><\/li>docker stop my_container<\/code>stops one container, while\u00a0docker stop $(docker ps -a -q)<\/code>\u00a0stops all running containers. A more direct way is to use\u00a0docker kill my_container<\/code>, which does not attempt to shut down the process gracefully first.<\/li>docker kill $(docker ps -q)<\/code><\/li>docker rm $(docker ps -a -q)<\/code><\/li>docker rmi $(docker images -q)<\/code><\/li><\/ul>\n\n\n\nCreate new container<\/h2>\n\n\n\n
