With this version, if you don't specify a tag whenpushing an image to Docker, Docker pushes only the image with the latest tag. If the latest tag doesn't exist, the push fails. To push an image with a specific tag to Docker, specify the tag in the docker pushbuild step. The following example pushes an image tagged prod: YAML steps:...- name: 'gcr.io/cloud-builders/docker' args: ['docker', 'push', '$$USERNAME/myrepo:prod']... JSON { ... { "name": "gcr.io/cloud-builders/docker", "args": [ "docker", "push", "$$USERNAME/myrepo:prod" ], } ...}To push all tags of an image to Docker, add the -a flag to the list of args in thedocker push build step: YAML steps:...- name: 'gcr.io/cloud-builders/docker' args: ['docker', 'push', '-a', '$$USERNAME/myrepo']...

You have three choices when if comes to running docker commands. Run the docker commands from the root user. Allow another user to perform "sudo" on the docker command, so all commands are run using "sudo docker ...". Create a group called docker and assign that to the user you want to run docker commands from. The documentation says, "Warning: The docker group grants privileges equivalent to the root user", so we should avoid this.In this case we want to run the docker commands from a user called "docker_user", so we add an entry in the "/etc/sudoers" file and use an alias in the user's ".bash_profile" file so we don't have to keep typing the "sudo" command.# useradd docker_user# echo "docker_user ALL=(ALL) NOPASSWD: /usr/bin/docker" >> /etc/sudoers# echo "alias docker="sudo /usr/bin/docker"" >> /home/docker_user/.bash_profile# su - docker_user$ docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES$For more information see: Docker Docker : All Articles Podman : Install Podman on Oracle Linux 8 (OL8) Configuring Docker StorageHope this helps.

Not currently being actively developed and is not considered to be as feature-rich or flexible as Kubernetes.What is the difference between Docker Swarm and Kubernetes?Docker Swarm is a simpler and more lightweight container orchestration platform than Kubernetes, with fewer features and capabilities for scaling and managing containerized applications.What is the difference between Docker Compose and Docker Swarm and Kubernetes?Docker Compose is a tool for defining and running multi-container Docker applications, while Docker Swarm and Kubernetes are container orchestration platforms for managing and scaling containerized applications across a distributed system.Why Kubernetes preferred over Docker Swarm?Kubernetes is preferred over Docker Swarm for its greater flexibility, scalability, and feature-richness and its ability to integrate with a wide range of other cloud and container technologies.What is the future of Docker Swarm?The future of Docker Swarm is uncertain, as it is not currently being actively developed and is not considered to be as feature-rich or flexible as Kubernetes.What is replacing Docker in Kubernetes?Docker is not being replaced in Kubernetes, but rather is one of several container formats and runtimes supported by the platform.Can Docker Swarm and Kubernetes coexist?Docker Swarm and Kubernetes can coexist in the same environment, but it may require careful management and configuration to ensure compatibility and avoid conflicts.What is the best alternative to docker compose?There are several alternatives to Docker Compose for defining and running multi-container Docker applications, including tools like Podman and Nomad and container orchestration platforms like Kubernetes and Docker Swarm.Is docker compose enough for production?While Docker Compose can be useful for defining and running multi-container Docker applications in a development or testing environment, it is generally not considered robust or feature-rich enough for production use, where more advanced container orchestration platforms like Kubernetes or Docker Swarm are typically employed.Why we use Kubernetes instead of Docker?Kubernetes is often used instead of Docker because it provides a more flexible and feature-rich platform for container orchestration and management, with capabilities for scaling, load balancing, and other advanced features not available in Docker alone.What is the drawback of Docker compose?One drawback of Docker Compose is that it can be limited in handling complex

A popular Linux distribution.bash: This is the command that is run inside the new Docker container. In this case, it starts a new Bash shell.Now, let’s see a simple example of how to use the ‘docker run bash’ command and understand its output.docker run -it debian bash# Output:# root@container_id:/#In this example, we’ve replaced ubuntu with debian, another popular Linux distribution. Like before, the docker run bash command starts a new Docker container from the Debian image and runs a Bash shell inside it. The output root@container_id:/# is the command prompt of the new Bash shell, indicating that you’re now inside the Docker container and ready to run commands.Intermediate Level: Running Scripts and ApplicationsAs you become more comfortable with the ‘docker run bash’ command, you can start to explore its more advanced uses. One common use case is running scripts or applications inside the Docker container.Let’s say you have a Python script that you want to run inside the container. You can do this by including the script in the ‘docker run bash’ command. Here’s how:docker run -it python:3.7 bash -c "echo 'print("Hello, Docker!")' > script.py && python script.py"# Output:# Hello, Docker!In this example, we’re using the ‘docker run bash’ command to start a new Docker container from the Python 3.7 image. The -c option allows us to run multiple commands in the Bash shell. We’re using it to create a Python script called script.py and then run that script using Python.The output Hello, Docker! is the result of running the Python script inside the Docker container. This demonstrates how you can use ‘docker run bash’ to run scripts or applications inside Docker containers, enabling a wide range of development and testing scenarios.Exploring Alternative Approaches to Docker InteractionsWhile ‘docker run bash’ is a powerful command, it’s not the only way to interact with Docker containers. Two other commands, ‘docker exec’ and ‘docker attach’, offer alternative methods of interaction.The ‘docker exec’ CommandThe ‘docker exec’ command allows you to run a command in a running Docker container. This is useful when you want to inspect a running container or debug a problem.Here’s an example of how to use the ‘docker exec’ command:docker run -d --name my_container ubuntu sleep infinity# Output:# container_iddocker exec -it my_container bash# Output:# root@container_id:/#In this example, we first start a new Docker container called ‘my_container’ using the ‘docker run’ command. The -d option tells Docker to run the container in detached mode, meaning it runs in the background. The sleep infinity command keeps the container running indefinitely.We then use the ‘docker exec’ command to start a Bash shell in the running container. The output root@container_id:/# indicates that we’re inside the Docker container.The ‘docker attach’ CommandThe ‘docker attach’ command allows you
