# Git Remote
###### tags:`git` `cheatsheet`
## Create SSH key
* ceate key
* get public key

     $ cat ~/.ssh/id_rsa.pub

* Gitlab
* `Settings` --> `SSH keys`
## Senario
### Add local repo to remote
1. create local repo (`git init`)
2. commit changes
3. create remote repo on GitLab
> Push it to GitLab directly to create the new project

    git push --set-upstream ssh://[e-mail]:7622/namespace/nonexistent-project.git master

### Clone from remote
1. create remote repo on GitLab
2. clone repo
3. commit changes
4. push to remote repo
## Operation
### Add remote repository

    $ git remote add origin <remote url>

* show

    $ git remote -v
    $ git remote show origin

### Push

    $ git push origin master
    $ git push origin master:master
    $ git push origin master:remote_master

> 「把本地的 master 分⽀推上去後， 在 Server 上更新 master 分⽀的進度， 或是如果不
存在該分⽀的話， 就建立⼀個 master 分⽀」
* show upstream

    $ git branch -vv

* set upstream

    $ git push -u origin master
    
    $ git branch -u origin master

    $ git branch -u origin/develop develop

`-u`: set upstream
> upstream: 每個分⽀可以設定⼀個「上游」, 它會指向並追蹤（track） 某個分⽀。
把 origin/master 設定為本地 master 分⽀的 upstream。
