docker image를 GHCR(GitHub Container Registry)에 업로드한 다음 같은 image ID를 갖는 여러 항목이 나타났다. 그동안 local machine에 있던 docker image를 GHCR에 업로드 했으니 더 이상 local host에 이미지가 없어도 되지 않을까 하는 생각에 원래 있던 image를 삭제하려고 하는데 이 경우 에러가 발생한다. cychong@mini1:~/work/slackbot$ docker images |grep slackbot my-slackbot latest 16cdaacd672e 5 days ago 133MB ghcr.io/cychong47/my-slackbot 0.1 16cdaacd672e 5 days ago 133MB ghcr.io/cychong47/slackbot 0.1 16cdaacd672e 5 days ago 133MB cychong@mini1:~/work/slackbot$ docker images |grep pocket pocket-retagger latest 942ef4cc7a60 2 days ago 285MB ghcr.

이상하게 wordpress 버전이 올라가면 docker용 wordpress 버전도 함께 올라갈 텐데 아무리 최신 docker image를 받아 container를 만들어도 wordpress admin 계정에 들어가면 wordpress를 업데이트 해야 한다고 한다. docket store(http://store.docker.com)에 가면 분명히 wordpress 최신 버전으로 패키징되어 있는 데… 혹시나 하고 ansible-playbook을 보니 /var/www/html에 마운트되는 위치에 이전 버전의 wordpress 파일들이 존재하고 있었다. volumes: - "/Users/cychong/Documents/wordpress/html:/var/www/html" - "/Users/cychong/Documents/wordpress/uploads:/var/www/html/wp-content/uploads" - "/Users/cychong/Documents/wordpress/conf/php_uploads.ini:/usr/local/etc/php/conf.d/uploads.ini" 바로 첫번째 줄이 문제를 유발하고 있는 곳… 내가 왜 굳이 저렇게 했을까 생각해 보니 저 디렉토리에 바로 wp-content가 있고, 그 아래 themes와 plugins가 있다.

YAML file state:absent 는 현재 존재하는 container를 중지시키고, 삭제한다. 단순히 stop만 시키려면 state:stopped로 지정하면 된다. pull: yes 옵션을 사용하면 항상 최신 image를 pull한다고 한다. recreate Use with present and started states to force the re-creation of an existing container. mbpr15:ansible cychong$ cat recreate_container_ghost.yaml --- - hosts: mini2 tasks: - name: Stop and remove contianer docker_container: name: ghost state: absent - name: Create ghost Container docker_container: name: ghost image: ghost # always pull the latest image pull: yes state: started recreate: yes volumes: - "/Users/cychong/Dropbox/Apps/ghost/content/:/var/lib/ghost/content" - "/Users/cychong/Dropbox/Apps/ghost/config.

Cloud Native Computing Foundation(http://cncf.io)에 포함된 Container monitoring tool. 집 맥미니에서 돌리고 있는 3개 container들을 관리하는데 사용할 수 있나 싶어(실은 관리할 것도 없지만 그냥 재미로 container monitor 기능을 보고 싶어서) 설치 해 봤다 Install cncf.io의 많은 툴이 그렇지만 golang으로 작성되어 있어 golang부터 설치했다 brew install go OSX에서 brew는 사용할 때마다 감탄을 금치 못하게 한다. 물론 우분투에도 apt가 있지만 apt보다 brew가 훨씬 편한 것 같다. 그 다음에는 그냥 docker hub에 있는 prometheus docker 가져다 설치
