ローカル repository に Github のアカウントを設定する、複数のアカウント設定に対応した方法 / How to set up a Github account in a local repository, with multiple accounts

注意: 予め現在の状態を壊さないようバックアップをしてください。

グローバル設定を止めて、リポジトリー内のローカル設定ファイルに設定を行う

{YOUR-ACCOUNT-1} 用の鍵を生成

$ cd ~/.ssh
$ ssh-keygen -t ed25519 -C "{YOUR-EMAIL@example.com}" -f id_rsa_github-{YOUR-ACCOUNT-1}

1 2	$ cd ~/.ssh $ ssh-keygen -t ed25519 -C "{YOUR-EMAIL@example.com}" -f id_rsa_github-{YOUR-ACCOUNT-1}

github に公開鍵を登録

$ code id_rsa_github-{YOUR-ACCOUNT-1}.pub

1	$ code id_rsa_github-{YOUR-ACCOUNT-1}.pub

Settings > SSH and GPG keys > New SSH key

~/.ssh/config の設定

$ code config

1	$ code config

# {YOUR-ACCOUNT-1}@github.com の為 のSSH設定を追加
# $ ssh -T github.com_{YOUR-ACCOUNT-1}
Host github.com_{YOUR-ACCOUNT-1}
    HostName github.com
    # User {YOUR-ACCOUNT-1}
    User git
    IdentityFile ~/.ssh/id_rsa_github-{YOUR-ACCOUNT-1}

# {YOUR-ACCOUNT-1}@github.com の為のSSH設定を追加

# $ ssh -T github.com_{YOUR-ACCOUNT-1}

Host github.com_{YOUR-ACCOUNT-1}

HostName github.com

# User {YOUR-ACCOUNT-1}

User git

IdentityFile ~/.ssh/id_rsa_github-{YOUR-ACCOUNT-1}

接続試験

$ ssh -T github.com_{YOUR-ACCOUNT-1}
Hi {YOUR-ACCOUNT-1}! You've successfully authenticated, but GitHub does not provide shell access.

1 2	$ ssh -T github.com_{YOUR-ACCOUNT-1} Hi {YOUR-ACCOUNT-1}! You've successfully authenticated, but GitHub does not provide shell access.

github のリポジトリーをクローン

クローン先: ~/work/src

$ mkdir -p ~/work
$ cd ~/work/
$ git clone git@github.com:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY} ./src

$ mkdir -p ~/work

$ cd ~/work/

$ git clone git@github.com:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY} ./src

リモートアドレスを登録

~/.ssh/config の設定に基づいて登録

$ cd src
$ git remote set-url origin git@github.com_{YOUR-ACCOUNT-1}:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY}.git

1 2	$ cd src $ git remote set-url origin git@github.com_{YOUR-ACCOUNT-1}:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY}.git

ユーザー名とメールアドレスを設定

グローバル設定は使わないので削除するか名前を変えておく

$ trash ~/.gitconfig

1	$ trash ~/.gitconfig

--local で設定する

$ git config --local user.email "{YOUR-EMAIL@example.com}"
$ git config --local user.name "{YOUR NAME}"

1 2	$ git config --local user.email "{YOUR-EMAIL@example.com}" $ git config --local user.name "{YOUR NAME}"

設定結果は下記のようになる

$ cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = git@github.com_{YOUR-ACCOUNT-1}:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY}.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "main"]
remote = origin
merge = refs/heads/main
[user]
email = {YOUR-EMAIL@example.com}
name = {YOUR NAME}

$ cat .git/config

[core]

repositoryformatversion = 0

filemode = true

bare = false

logallrefupdates = true

[remote "origin"]

url = git@github.com_{YOUR-ACCOUNT-1}:{YOUR-ACCOUNT-1}/{YOUR-REPOSITORY}.git

fetch = +refs/heads/*:refs/remotes/origin/*

[branch "main"]

remote = origin

merge = refs/heads/main

[user]

email = {YOUR-EMAIL@example.com}

name = {YOUR NAME}
