pass "`--rm`" to remove container when it stops. #### List all containers (pass -a to see all containers) ``` docker container ls [-a] ``` #### Get logs from container ``` docker container logs ``` #### List running processes in the container ``` docker container top ``` #### Get system information about running containers ``` docker container stats ``` #### Get metadata about running container ``` docker container inspect ``` Example: ```javascript [ { "Id": "2471fee7e410a4ba48e69e80ecdc7033f46f7012ca493d1dba92dc9a6fda46f7", "Created": "2020-01-13T01:27:41.8547458Z", "Path": "nginx",

```bash docker container stop ``` #### Remove container (pass -f to force remove container) ```bash docker container [-f] rm ``` #### Start container with different process then defined in CMD or ENTRYPOINT ```bash docker container run -it --name webserver nginx bash ``` will start "bash" in interactive mode in "nginx" container named "webserver". Once connected, a "ps" can be installed to make sure the only process running is "bash" ```bash apt-get update apt-get install -y procps ps aux ``` #### Connect to the running docker container and run shell Connect to running container with shell (depends whether specific shell is installed) ```bash docker container exec -it bash ``` #### List container port mappings: ```bash docker container port ``` if container has a host to container port mappings, command should produce something like:\ `80/tcp -> 0.0.0.0:80` --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://notebook.iuriioapps.com/containers-and-microservices/docker/containers.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
