위 명령어로 argocd namespace를 생성하고 install 한다.(이때 네임스페이스명은 꼭 argocd로 하는 것이 좋다.)

 

brew install argocd

root@datapecker3:/opt/apps/woodpecker# brew install argocd
Command 'brew' not found, did you mean:
  command 'qbrew' from deb qbrew (0.4.1-8build1)
  command 'brec' from deb bplay (0.991-10build1)
Try: apt install <deb name>

brew 명령어로 argocd를 설치해야 한다. brew가 설치되어 있지 않으면 먼저 설치하자!

[Linux] brew 설치 방법

 

brew 설치 후 명령을 실행하면 아래와 같이 다운로드가 진행될 것이다. 많이 기다려야 한다.

user@datapecker3:/home$ brew install argocd
==> Auto-updating Homebrew...
Adjust how often this is run with HOMEBREW_AUTO_UPDATE_SECS or disable with
HOMEBREW_NO_AUTO_UPDATE. Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
==> Homebrew collects anonymous analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics
No analytics have been recorded yet (nor will be during this `brew` run).

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations

네트워크 접속 설정

Load Balancer or Port Forwarding

kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'
kubectl port-forward svc/argocd-server -n argocd 8080:443

본인의 환경에 맞게 둘 중 하나를 실행시키자.

필자는 포트포워딩으로 띄울 것이기 때문에 영구적으로 실행하고 로그를 남길 수 있게 문법을 작성하여 아래 명령어로 실행하였다.

nohup kubectl port-forward --address=0.0.0.0 -n argocd svc/argocd-server 8080:443>> /opt/apps/kubernetes/logs/argocd.out 2>&1 &

 

여기까지 진행하였다면 ${master host ip}:8080를 입력하여 argocd 사이트에 접속한다.

admin 패스워드 확인하기

argocd admin initial-password -n argocd

user@datapecker3:/home$ argocd admin initial-password -n argocd
TcTg2kgGdkhmdh7o

 This password must be only used for first time login. We strongly recommend you update the password using `argocd account update-password`.

admin / TcTg2kgGdkhmdh7o 를 입력하여 로그인한다.
