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 docker_containers:
|
|
|
|
- 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={{inventory_hostname}}:{{item['HostConfig']['PortBindings']['8080/tcp'][0]['HostPort']}}
|
|
with_items: docker_containers
|
|
|
|
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="{{inventory_hostname}}:{{docker_containers[{{item}}]['HostConfig']['PortBindings']['8080/tcp'][0]['HostPort']}}"
|
|
with_sequence: start=0 end={{start_containers_count - 1}}
|
|
|
|
Stop, remove all of the running tomcat containers and list the exit code from the stopped containers:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- name: stop tomcat servers
|
|
docker: image=centos command="service tomcat6 start" state=absent
|
|
- name: Display return codes from stopped containers
|
|
debug: msg="Returned {{inventory_hostname}}:{{item}}"
|
|
with_items: docker_containers
|
|
|
|
Create a named container:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- name: run tomcat server
|
|
docker: image=centos name=tomcat command="service tomcat6 start" ports=8080
|
|
|
|
Create multiple named containers:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- name: run tomcat servers
|
|
docker: image=centos name={{item}} command="service tomcat6 start" ports=8080
|
|
with_items:
|
|
- crookshank
|
|
- snowbell
|
|
- heathcliff
|
|
- felix
|
|
- sylvester
|
|
|
|
Create containers named in a sequence:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- name: run tomcat servers
|
|
docker: image=centos name={{item}} command="service tomcat6 start" ports=8080
|
|
with_sequence: start=1 end=5 format=tomcat_%d.example.com
|
|
|
|
Create two linked containers:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- name: ensure redis container is running
|
|
docker: image=crosbymichael/redis name=redis
|
|
|
|
- name: ensure redis_ambassador container is running
|
|
docker: image=svendowideit/ambassador ports=6379:6379 links=redis:redis name=redis_ambassador_ansible
|
|
|
|
Create containers with options specified as key-value pairs and lists:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
- docker:
|
|
image: namespace/image_name
|
|
links:
|
|
- postgresql:db
|
|
- redis:redis
|
|
|
|
|
|
Create containers with options specified as strings and lists as comma-separated strings:
|
|
|
|
- hosts: web
|
|
sudo: yes
|
|
tasks:
|
|
docker: image=namespace/image_name links=postgresql:db,redis:redis
