9. How can several nodes share Docker containers?
It is possible to share Docker containers on different nodes with the Docker Swarm. Docker Swarm is a tool that allows IT administrators and developers to create and manage a cluster of swarm nodes within the Docker platform. A swarm consists of two types of nodes: a manager node and a worker node.
10. Which commands are used to build a Docker swarm?
Wherever you wish to run your management node, create a swarm.
MANAGER-IP>:/docker swarm init —advertise-addr
You can include worker nodes in your swarm once you’ve established one on your manager node. A node creates a token right away when it is started as a manager. The worker node’s host machine has to run the following command (token) in order to construct a worker node.
11. How do you run multiple containers using a single service?
With Docker Compose, several containers can operate as a single service. Each container operates independently but is still capable of communication. YAML files make up every Docker Compose file.
12. What is the purpose of the expose and publish commands in Docker?
- An instruction used in Dockerfile is called expose.
- Within a Docker network, it is used to expose ports.
- This documentation instruction is used while creating an image and starting a container.
- The Docker command is called expose.
- Expose 8080, for instance.
- A Docker run command uses the Publish command.
- It is applicable outside of the Docker environment.
- A host port is mapped to an active container port using it.
- In Docker, the command is - publish or -p.

git diff-tree -r 87e673f21b.
The -r argument tells the program to list specific files.
All the files that were modified or added are listed in the commit hash.
2. How do you push a file from your local system to the GitHub repository using Git?
The local repository should first be linked to the remote repository:
/Example: https://github.com/Btreesystem-github/test.git git remote add origin
Put your file in the remote repository second:
push origin master on git
3. What is Git stash?
While working on a branch, a developer wants to switch to another branch to work on something different but doesn’t want to make modifications to your incomplete work.
Git stash is the answer to this problem. Git stash puts your updated tracked files on a stack of incomplete changes that you can apply again whenever you want.
4. What is a merge conflict in Git, and how can it be resolved?
Git requires your assistance in determining which changes to include in the final merge when merge branches with competing commits exist.
Select the modifications you want to maintain in the final merging by manually editing the conflicting file.
- Use the GitHub conflict editor to resolve
- When fighting for line modifications results in a merge dispute, this is the action taken. This may happen, for instance, if different persons in your Git repository make different changes to the same line of a particular file on several branches.
- Using the conflict editor to resolve a merge conflict: Click “Pull requests” under the name of your repository.
- Click “Resolve conflicts” near the bottom of your pull request to start.
- Choose whether you want to maintain changes from just your branch, changes from the other branch, or a new modification that might include changes from both branches.
- The conflict marks, ======, and <<<<<< should be removed. and make any modifications you desire for the final merging.
- Click Mark as resolved once you have resolved all of the conflicts in the file.
- Click Commit merge once you’ve addressed any merge conflicts. This unifies your head branch with your entire base branch.
- Using the command line, a merge dispute is resolved. Launch Git Bash.
- Go to the local Git repository that has the merge conflict and enter it.
- Generate a list of the files that the merge conflict affects. In this example, the file styleguide.md contains a merge conflict.
Add or stage your changes
Commit your changes with a comment
The branches can now be combined using the command line, or you can send your modifications to a remote repository on GitHub and combine them in a pull request.
Below is a table that lists some of the Basic Git Commands.
5. Describe some fundamental commands for Git.
