Question

我使用docker-compose运行Laravel项目并希望使用ansible进行部署，并简化本地环境的配置过程

以下是我使用的ansible剧本的一部分以及导致问题的原因：

f <- "as.integer"
v <- NA
do.call(f, list(v))

输出：

 # run docker-compose
- name: Run docker containers
  shell: docker-compose -f {{compose_file}} up -d

- name: Docker ps
  shell: docker-compose -f {{compose_file}} ps
  register: lists

- name: Print docker ps
  debug: msg="{{lists.stdout_lines}}"

# run migrations
- name: Run migrations
  shell: docker-compose -f {{compose_file}} exec -T --user {{wwwdata}} workspace sh -c 'cd {{remote_basedir}} && php artisan migrate --seed'

正如您所看到的那样，当TASK [Run docker containers] ************************************************************************* changed: [localhost] TASK [Docker ps] ************************************************************************* changed: [localhost] TASK [Print docker ps] ************************************************************************* ok: [localhost] => { "msg": [ " Name Command State Ports ", "------------------------------------------------------------------------------------------------------", "docker_applications_1 /true Exit 0 ", "docker_mailcatcher_1 mailcatcher --foreground - ...

感谢您的回复！

感谢Tarun Lalwani我开始朝着正确的方向前进，而不是使用他提出的bash脚本，我用这样的方式用ansible做了

- name: wait for mysql container
  retries: 5
  delay: 5
  shell: docker-compose -f {{compose_file}} exec -T  mysql sh -c 'mysql --user=db_user --password=secret -e "SHOW DATABASES;" | grep -c database'
  register: mysql_alive
  until: mysql_alive.rc == 0

从docker容器运行命令时，Ansible，mysql连接被拒绝
