## Step (1.3) Configure git remote repository locally
Workshop用https以帳號密碼登入Github的方式已不再支援。

> git remote add origin https://github.com/$GITHUB_USERNAME/front-app-repo.git

remote: Support for password authentication was removed on August 13, 2021.
remote: Please see https://docs.github.com/en/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication.
fatal: Authentication failed for 'https://github.com/chubbychia/front-app-repo.git/'

改用ssh keypair login，設定：
1. 在cloud9 gen keypair

> ssh-keygen -t ecdsa -f ~/.ssh/id_ecdsa 
> chmod 400 ~/.ssh/id_ecdsa 

2. 修改ssh config

> vi ~/.ssh/config 
====
Host github.com (http://github.com/) 
    IdentityFile ~/.ssh/id_ecdsa 
    IdentitiesOnly yes
===
> chmod 400 ~/.ssh/config 

若不熟悉vi，從Cloud9打開隱藏檔和顯示Home目錄，從文字編輯器中修改 (/home/ec2-user/.ssh/config)

3. Github -> Profile -> Setttings -> SSH and GPG keys -> New SSH Key
複製public key到SSH Key中，取名MyPubKey

> cat ~/.ssh/id_ecdsa.pub
===
ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBKJi0LfRi50D8qRB19GJWUJkE6QZJGFatmpiFoPd7g5J/dIC1RSs0vGfvGwWFFIotzk76WLlxBoOJ4PdNvgzHnw= [e-mail]

4. 把workshop連github的指令從https改為ssh

> git remote add origin ${YOU_GIT_SSH_URL}
> git push -v origin main

5. 將改完的程式碼段落貼上Cloud9執行

## Step (9.1) Setup Github Repository URL to ArgoCD
先到Settings編輯git相關資訊
把Username和Github personal token更新至連線設定
再按照Workshop步驟建立application，設定k8s manifest 的Github URL（使用https URL)

## Step (11) 取得frontend LoadBalancer的endpoint
Workshop有誤，把ingress/backend-ingress改為ingress/frontend-ingress

echo http://$(kubectl get ingress/frontend-ingress -o jsonpath='{.status.loadBalancer.ingress[*].hostname}')
