Old docker instances got deleting every time

Open Source Projects DockerEngine

Hi,

I’ve create an ansible project which uses “docker_compose” to compose my docker-compose.yml file present in the following directory.

[root@jyothishvv tasks]# cat docker-compose.yml
version: “3”
services:
webserver:
build:
context: ./DF
container_name: “{WEBSERVER_HTTP_CONTAINER_APPNAME}" restart: 'always' ports: - "{WEBSERVER_HTTP_CONTAINER_PORT1}:80”
- “{WEBSERVER_HTTP_CONTAINER_PORT2}:443" volumes: - "/opt/shared/{WEBSERVER_HTTP_CONTAINER_USERNAME}/public_html:/var/www/html”
- “/opt/shared/{WEBSERVER_HTTP_CONTAINER_USERNAME}/php/php.ini:/usr/local/etc/php/php.ini" - "/opt/shared/{WEBSERVER_HTTP_CONTAINER_USERNAME}/vhosts:/etc/apache2/sites-enabled”
- “/opt/shared/${WEBSERVER_HTTP_CONTAINER_USERNAME}/logs:/var/log/apache2”

Also, my docker ansible-playbook is given below.
[root@jyothishvv tasks]# cat main.yml

  • name : Run docker-compose using ansible
    docker_compose:
    project_src: /opt/playbook/hosting/roles/webserver/tasks
    state: present

I have created an environment file with following content.

[root@jyothishvv hosting]# cat env.sh
#!/bin/bash
export WEBSERVER_HTTP_CONTAINER_USERNAME=lmdapp1usr
export WEBSERVER_HTTP_CONTAINER_APPNAME=lmdapp1
export WEBSERVER_HTTP_CONTAINER_PORT1=2000
export WEBSERVER_HTTP_CONTAINER_PORT2=2043
export DBSERVER_MYSQL_CONTAINER_PORT1=3000
export CACHESERVER_REDIS_CONTAINER_PORT1=6000
export DBSERVER_MYSQLMGMT_CONTAINER_PORT1=8000

During the first time when I run this ansible-playbook using this docker-compose file the following docker instances were created succesfully.
[root@jyothishvv hosting]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8305621908a2 redis:latest “docker-entrypoint.s…” 18 minutes ago Up 18 minutes 0.0.0.0:6000->6379/tcp lmdapp1_redis
88701e279616 phpmyadmin/phpmyadmin “/docker-entrypoint.…” 18 minutes ago Up 18 minutes 0.0.0.0:8000->80/tcp lmdapp1_phpmyadmin
9d236b427647 mysql:5.6.44 “docker-entrypoint.s…” 18 minutes ago Up 18 minutes 0.0.0.0:3000->3306/tcp lmdapp1_mysql_5.6
96b47df264e3 tasks_webserver “/usr/sbin/apache2ct…” 18 minutes ago Up 18 minutes 0.0.0.0:2000->80/tcp, 0.0.0.0:2043->443/tcp lmdapp1

But while I changed the env.sh details as follows and executing ansible-playbook, instead of creating new docker instances along with old instances, it is deleting all the old ones and creating new one.
changed env.sh is given below:
[root@jyothishvv hosting]# cat env.sh
#!/bin/bash
export WEBSERVER_HTTP_CONTAINER_USERNAME=lmdapp2usr
export WEBSERVER_HTTP_CONTAINER_APPNAME=lmdapp2
export WEBSERVER_HTTP_CONTAINER_PORT1=2001
export WEBSERVER_HTTP_CONTAINER_PORT2=2044
export DBSERVER_MYSQL_CONTAINER_PORT1=3001
export CACHESERVER_REDIS_CONTAINER_PORT1=6001
export DBSERVER_MYSQLMGMT_CONTAINER_PORT1=8001

Can any body address my problem. If you are not clear about the issue, please let me know.

Uhm, didn’t you forget to share the task in the ansible role?
