How to Upload a Project on Github using the command line?

1.Create a new repository on GitHub.
2.Open Git Bash command line terminal.
3.Copy current working directory to your local project.

4.Initialize the local directory as a Git repository.
-> git init
5.Add the files to your new local repository. This stages them for the first commit.
-> git add .
6.Commit the files that you’ve staged in your local repository.
-> git commit -m "initial commit message"
7.Copy the HTTPS URL of your newly created GitHub repo,In the Command prompt, add the URL for the remote repository where your local repository will be pushed.
-> git remote add origin <remote repository URL>
-> git remote -v
Push the changes in your local repository to GitHub repository
-> git push -f origin master

That’s all

====== Docker =======
What Is Docker?
Docker is an open source platform to develop, ship, and run applications, more commonly known as a container manager.

What Is a Docker Machine?
A Docker machine is a utility that lets you install Docker on virtual hosts, and then manage those hosts from the command line.

1. docker --version - Docker version

####List of Docker Commands####

##Docker Container Commands

1. docker create <IMAGE NAME> - Create a container (without starting it)
2. docker rename <CONTAINER_NAME> <NEW_CONTAINER_NAME> - Rename an existing container
3. docker run [IMAGE] [COMMAND] - Run a command in a new container
4. docker run --rm [IMAGE] – removes a container after it exits.
5. docker run -td [IMAGE] – starts a container and keeps it running.
6. docker run -it [IMAGE] – starts a container, allocates a pseudo-TTY connected to the container’s stdin, and creates an interactive bash shell in the container.
7. docker run -it-rm [IMAGE] – creates, starts, and runs a command inside the container. Once it executes the command, the container is removed.
8. docker rm <CONTAINER NAME> - Delete a container (if it is not running)
9. docker update <CONTAINER NAME> - Update the configuration of one or more containers:

##Starting and Stopping Containers
How to start and stop processes in a particular container.

10. docker start <CONTAINER NAME> - Start a container
11. docker stop <CONTAINER NAME> - Stop a running container
12 docker restart <CONTAINER NAME> - Stop a running container and start it up again
13. docker pause <CONTAINER NAME> - Pause processes in a running container
14. docker unpause <CONTAINER NAME> - Unpause processes in a running container
15. docker wait <CONTAINER NAME> - Block a container until others stop (after which it prints their exit codes)
16 docker kill <CONTAINER NAME> - Kill a container by sending a SIGKILL to a running container
17. docker attach <CONTAINER NAME> - Attach local standard input, output, and error streams to a running container

## Docker Image Commands
All the necessary commands for working with Docker images.

18. docker build [URL] - Create an image from a Dockerfile
19. docker build -t – builds an image from a Dockerfile in the current directory and tags the image
20. docker pull [IMAGE] - Pull an image from a registry
21. docker push [IMAGE] - Push an image to a registry
22. docker import [URL/FILE] - Create an image from a tarball
23. docker commit <CONTAINER NAME> [NEW_IMAGE_NAME] - Create an image from a container
24. docker rmi [IMAGE] - Remove an image
25. docker load [TAR_FILE/STDIN_FILE] - Load an image from a tar archive or stdin
26. docker save [IMAGE] > [TAR_FILE] - Save an image to a tar archive, streamed to STDOUT with all parent layers, tags, and versions

##Docker Commands for Container and Image Information

27. docker ps - List running containers
28. docker ps -a – lists both running containers and ones that have stopped
29. docke image ls - List all images that are locally stored with the docker engine
30. docker inspect [OBJECT_NAME/ID] - List low-level information on Docker objects
31. docker events <CONTAINER NAME> - List real-time events from a container
32. docker port <CONTAINER NAME> - Show port (or specific) mapping for a container
33. docker top <CONTAINER NAME> - Show running processes in a container
34. docker stats <CONTAINER NAME> - Show live resource usage statistics of containers
35. docker diff <CONTAINER NAME> - Show changes to files (or directories) on a filesystem
36. docker logs <CONTAINER NAME> - List the logs from a running container
37. docker history [IMAGE] - Show the history of an image

##Networks

38. docker network ls - List networks
39. docker network rm <NETWORK NAME> - Remove one or more networks
40. docker network inspect <NETWORK NAME> - Show information on one or more networks
41. docker network connect <NETWORK NAME> <CONTAINER> - Connects a container to a network
42. docker network disconnect <NETWORK NAME> <CONTAINER> - Disconnect a container from a network

Hi,

I just started a Learning Group, and I’d love to have you as a member. You are hereby invited to join the new.

A Lean In group is a small group of technicians who meet on Facebook to support each other and learn new skills. Our "Full Stack Java Developer Community" will be a place where we can be unapologetically ambitious, expand our networks, and help each other achieve our goals.

We’ll dive into a different topic ranging from identifying our strengths to combating bias at work. Lean In has teamed up with leading experts to create and activities that will guide our discussions.

I think you’d be a wonderful addition to the group and hope you’ll consider joining us.
