How to use docker-php-ext-install command on the docker_container of ansible modules.

I faced any problems that is couldn't use command option of a docker_container module.

I need customize php-fpm container, so I used command in docker_container's command option. But I had any struggle points.

My struggles..

1. I didn't recognize command option's reference detail. Is parameter type string? list?  fmm??
2. Importance of ENTRYPOINT(docker-php-entrypoint?? what's this?)
3. In using **command option,**Docker container shutting down immediately.
   • PHP-fpm container is uses exposed port. Why shutting down????

How to

Let me get straight the point, this playbook is a my solution.

yaml
1- name: Deploy PHP7 on docker container
2    docker_container:
3      name: php7-fpm
4      auto_remove: yes
5      command: [
6        "bash",
7        "-c","
8        'apt update && apt install zlib1g-dev && docker-php-ext-install zip && docker-php-ext-install pdo_mysql && php-fpm'"
9      ]
10      image: php:7-fpm
11      exposed_ports:
12        - 9000
13      state: started
14

Answer of my struggles

 1.

A command option of docker_container can receive one of shell command.

["ping","127.0.0.1","-c","5"]

"ping 127.0.0.1 -c 5"

Both styles can use too.

2.

"docker-php-entrypoint" distinguish argument's -

If entrypoint option and command option that both have a some parameter, Executing that the command option is option of entrypoint's.

3.

PHP7-fpm docker container runs php-fpm shell command on the command that is equivalent of dockerfile's CMD directive. However, my wrong playbook didn't have php-fpm command at last. Therefore all commands successfully done, and container shutting down.

yaml
1command: [
2        "bash","-c","'apt update && apt install zlib1g-dev && docker-php-ext-install zip && docker-php-ext-install pdo_mysql"
3      ]

So, bash commands option helped my solution.

"/bin/bash -c '{any commands of combined from &&}'"

Please your advices, comments.

thanks.
