SSH認証キーをGitLabに登録して、リモートリポジトリからクローンする方法についてです！
0-1. 全体の流れ
0-2. 本記事の対象者
- SSH認証キーをGitLabに登録したい
- SSH接続でリモートリポジトリをクローンしたい
0-3. 前提条件
- GitLabアカウント作成済み
- GitLabでプロジェクト作成済み(本記事では『test』)
- 隠しファイル表示設定済み
0-4.要件
- GitLab登録
- SSH秘密鍵 / SSH公開鍵 / OpenSSHキー
- git clone
1.SSH
1-1.キーペア作成(秘密鍵と公開鍵)
local
$ cd ~/.ssh
$ ssh-keygen -t rsa -f gitlab_rsa -C hoge@gmail.com
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): #お好みのパスワードを入力
Enter same passphrase again: #再度お好みのパスワードを入力
Your identification has been saved in gitlab_rsa
Your public key has been saved in gitlab_rsa.pub
The key fingerprint is:
SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx hoge@gmail.com
$ ls ~/.ssh
gitlab_rsa. gitlab_rsa.pub
1-2.GitLabに公開鍵を登録
local
$ pbcopy < ~/.ssh/gitlab_rsa.pub
- GitLabの
SSH Keysにアクセス -
SSH Fingerprintsにpbcopyでコピーしたgitlab_rsaをペースト - Titleは任意(gitlab_rsaなど)
1-3.ssh-agentに秘密鍵を登録
local
$ ssh-add ~/.ssh/gitlab_rsa
Identity added: /Users/xxxxxxxxxxxxxxx/.ssh/gitlab_rsa (xxxxxxxxxxxxxxxxxxx@gmail.com)
$ ssh-add -l
xxxx SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx@gmail.com (RSA)
1-4.configに反映
local
$ vim ~/.ssh/config
# GitHub
Host github.com
IdentityFile ~/.ssh/github_rsa
User git
# GitLab
Host gitlab.com
HostName gitlab.com
User git
AddKeysToAgent yes
UseKeychain yes
TCPKeepAlive yes
identitiesonly yes
IdentityFile ~/.ssh/gitlab_rsa
1-5.SSH接続
local
$ ssh gitlab.com
The authenticity of host 'gitlab.com (xxxx:xxxx:xx:x:xxxx:xxxx:xxxx:xxxx)' can't be established.
ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes #yesを入力
Warning: Permanently added 'gitlab.com' (ED25519) to the list of known hosts.
Enter passphrase for key '/Users/kishimotokazuma/.ssh/gitlab_rsa': #パスワード入力
