EXAMPLES = '''
Start one docker container running tomcat in each host of the web group and bind tomcat's listening port to 8080
on the host:
- hosts: web
sudo: yes
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=:8080
The tomcat server's port is NAT'ed to a dynamic port on the host, but you can determine which port the server was
mapped to using $DockerContainers:
- hosts: web
sudo: yes
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=8080 count=5
- name: Display IP address and port mappings for containers
debug: msg="Mapped to {{inventory_hostname}}:{{item.NetworkSettings.PortMapping.Tcp['8080']}}"
with_items: $DockerContainers
Just as in the previous example, but iterates over the list of docker containers with a sequence:
- hosts: web
sudo: yes
vars:
start_containers_count: 5
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=8080 count={{start_containers_count}}
- name: Display IP address and port mappings for containers
debug: msg="Mapped to {{inventory_hostname}}:{{DockerContainers[{{item}}].NetworkSettings.PortMapping.Tcp['8080']}}"
with_sequence: start=0 end={{start_containers_count - 1}}
Stop and remove all of the running tomcat containers:
- hosts: web
sudo: yes
tasks:
- name: stop tomcat servers
docker: image=centos command="service tomcat6 start" state=absent
