Getting Docker Container ID from Container Name

What is the ‘hello-world’ Docker image?

A basic container image called ‘hello-world’ is used to confirm that Docker is installed and operating as intended. After printing “Hello from Docker!”, it leaves.

What causes the hello-world container to disappear right away?

The ‘hello-world’ container is meant to execute a short script that outputs a message before shutting down. This action is typical and shows that the image ran well.

How we can view every container, even the ones that have been exited?

With the help of docker ps -a command docker list all containers, including those that have exited.

When a container exits, can we resume it?

Yes, we can restart an exited container using the docker start command followed by the Container ID or name: docker start hello_container.

How can the hello-world container be removed?

We can remove the ‘hello-world’ container using the docker rm command followed by the Container ID or name: docker rm hello_container.

Docker is a platform that allows developers to design, deploy, and manage programs within lightweight, portable containers. Containers bring together a program and its dependencies to maintain consistency across environments. Container management is critical in DevOps, and one typical duty is obtaining the Docker container’s ID by name. This course will take you through each level, teaching you key ideas and activities along the way.

Primary Terminologies

• Docker: It is an open-source technology that makes it easier to automate the deployment of apps within portable, light containers. It offers a dependable setting for testing, production, and development.
• Container: A software program or service that may operate independently is called a Docker container.
• Container ID: The unique number or identity of each individual container used to store a particular kind of material.
• Container Name: A name for a container that is readable by humans. Users can give meaningful names to containers for better administration, even though Docker will assign a random name if none is provided.
