ssh-keygenでキーの生成

sshで接続するためにssh keyの生成を行います。

ssh-keygen -t ed25519 -C "your_email@example.com"

Multipass VMのIPアドレスを確認する

% multipass list
Name                    State             IPv4             Image
real-bream              Stopped           --               Ubuntu 22.04 LTS
test                    Running           192.168.64.15    Ubuntu 22.04 LTS

ホスト側の~/.ssh/configに接続先情報を追記する

Host <識別名>
  Hostname <IPアドレス>
  Post 22
  identityFile ~/.ssh/<秘密鍵>
  User ubuntu

公開暗号キーをコピーする

cat ~/.ssh/<公開鍵.pub>
pbcopy < ~/.ssh/<公開鍵.pub>

Multipass VMの~/.ssh/authorized_keysに追記する

multipass shell <host>
vim ~/.ssh/authorized_key
cat ~/.ssh/authorized_key

% multipass shell test
