access docker container

Accessing and managing Docker containers can be easily done using a sequence of commands. This article provides a simple guide to help you access your Docker container.

The primary pre-requisite is that Docker should be installed already on your system. If Docker is not yet installed, you can download and install it through the official Docker website.

Step 1: List the Docker Containers

Access to a Docker container commences with the ability to view and identify containers. This can be done by using the Docker Command-Line Interface (CLI).

Navigate to your system’s command terminal. Type and execute this command:

docker ps -a

The “docker ps -a” command lists all Docker containers present on your system, whether they are running or have been stopped.

Step 2: Identify the Docker Container to Access

On executing the command in step 1, you’re shown the list of Docker containers with pertinent details about them. This includes their unique ID, status, name, and others. It’s important to identify the container to be accessed by noting down its ID or name.

Step 3: Access the Docker Container

With the identity of the Docker container confirmed, the next step is to access it. Docker provides a command-line interface for this purpose. You can execute the following command:

docker exec -it [container-id] /bin/bash

Replace “[container-id]” with either the ID or name of the intended Docker container. This command basically tells Docker to execute the “/bin/bash” command in your specified Docker container for interactive terminal communication (-it).

Step 4: Use the Docker Container

At this point, you can now execute commands in your Docker container’s terminal as per your requirements. This might be executing a program, checking logs, or inspecting processes - anything that you want to do inside the container.

Step 5: Exiting the Docker Container

After interacting with your Docker container, you can exit it by simply typing and executing the “exit” command at the terminal prompt.

exit

Remember, exiting your Docker container’s shell does not stop the container from running. It just ends the interactive communication session.

To sum up, accessing a Docker container is a fairly straightforward process that includes listing the Docker containers using ‘docker ps -a’, identifying the container to be accessed by noting its ID or name, accessing the container using ‘docker exec -it’, and exiting it with ‘exit’.
