B. Explore Docker Containers
- Get a Docker Container Image. We need to have a local copy of the Docker container image in order to test it. ...
- Explore the Container Interactively. To actually explore a container, run this command: $ docker run -it --rm=true username/image:tag /bin/bash. ...

What is the command in Docker to list all running containers?
A Docker container is a standalone runtime instance of an image. To list Docker containers, use the docker container ls command or its alias docker ps .
Where is the Docker container directory?
to find the root directory of docker. You will find the docker directory will be given in this line: "Docker Root Dir: /var/lib/docker". The docker images, they are stored inside the docker directory: /var/lib/docker/ images are stored there.
How do I run a docker container?
The basic syntax for the command is: docker run [OPTIONS] IMAGE [COMMAND] [ARG...] You can run containers from locally stored Docker images. If you use an image that is not on your system, the software pulls it from the online registry.
How do I stop all Docker containers?
kill all running containers with docker kill $(docker ps -q) delete all stopped containers with docker rm $(docker ps -a -q)
How do I bring up Docker daemon?
The Docker daemon log can be viewed by using one of the following methods:
- By running journalctl -u docker. service on Linux systems using systemctl.
- /var/log/messages , /var/log/daemon. log , or /var/log/docker. log on older Linux systems.
What is the Docker Run command?
The docker run command creates a container from a given image and starts the container using a given command. It is one of the first commands you should become familiar with when starting to work with Docker.
How do I access containers?
To get access to the container logs you should prefer using the docker logs command. To detach from the container without stopping it, use the CTRL-p CTRL-q key combination. Pressing CTRL-c stops the container. If the running processes you are attaching to accepts input, you can send instructions to it.
How do I run a docker image?
Do the following steps:
- $ docker images. You will get a list of all local Docker images with the tags specified.
- $ docker run image_name:tag_name. If you didn't specify tag_name it will automatically run an image with the 'latest' tag. Instead of image_name , you can also specify an image ID (no tag_name).
How do I view Docker images?
In order to list and format Docker images, you have to use the “docker images” command followed by the “–format” option and a Go template.
How do I access Docker files?
Accessing the Docker containers
- On the host machine, go to the Docker working directory where you earlier deployed the Docker image package files (/mdm).
- Run the Docker list command to get a list of all the Docker containers running in your system: docker container ls.
- For terminal access, attach to each InfoSphere MDM Docker container, as needed.
How do I run a docker container locally?
docker commands
- build docker image. docker build -t image-name .
- run docker image. docker run -p 80:80 -it image-name.
- stop all docker containers. docker stop $(docker ps -a -q)
- remove all docker containers. docker rm $(docker ps -a -q)
- remove all docker images. ...
- port bindings of a specific container. ...
- build. ...
- run.
Is docker image OS dependent?
No, it does not. Docker uses containerisation as a core technology, which relies on the concept of sharing a kernel between containers. If one Docker image relies on a Windows kernel and another relies on a Linux kernel, you cannot run those two images on the same OS.
How do I run Docker container infinitely?
- In your Dockerfile use this command: CMD ["sh", "-c", "tail -f /dev/null"]
- Build your docker image.
- Push it to your cluster or similar, just to make sure the image it's available.
- kubectl run debug-container -it --image=<your-image>
