I went through the documentation provided here
https://docs.ansible.com/ansible/latest/collections/community/aws/ecs_taskdefinition_module.html
It gives me nice examples of setting of Fargate task definition. However it showcases example with only one port mapping and there is no mount point shown here. I want to dynamically add port mappings ( depending on my app) and volume/mount points
For that I am defining my host_var for app as below ( there can be many such apps with different mount points and ports)
---
task_count: 4
task_cpu: 1028
task_memory: 2056
app_port: 8080
My Task definition yaml file looks like below
- name: Create/Update Task Definition
ecs_taskdefinition:
aws_access_key: "{{....}}"
aws_secret_key: "{{....}}"
security_token: "{{....}}"
region: "{{....}}"
launch_type: FARGATE
network_mode: awsvpc
execution_role_arn: "{{ ... }}"
task_role_arn: "{{ ...}}"
containers:
- name: "{{...}}"
environment: "{{...}}"
essential: true
image: "{{ ....}}"
logConfiguration: "{{....}}"
portMappings:
- containerPort: "{{app_port}}"
hostPort: "{{app_port}}"
cpu: "{{task_cpu}}"
memory: "{{task_memory}}"
state: present
I am able to create/update the task definition.
New requirements are that
- Instead of one port, now we can have multiple(or none) port mappings.
- We will have multiple (or none) mount points and volumes as well
Here is what I think the modified ansible host_var should look like below for ports [container_port1:host_port1, container_port2:host_port2, container_port3:host_port3]
task_count: 4
task_cpu: 1028
task_memory: 2056
#[container_port1:host_port1, container_port2:host_port2, container_port3:host_port3]
app_ports: [8080:80, 8081:8081, 5703:5703]
I am not sure what to do in ansible playbook to run through this list of ports.
Another part of the problem is that, although I was able to achieve creating volume and mouting in container thorough aws console, I was not able to do same using ansible.
here is the snippet of json for the AWS fargate looks like ( for volume part). There can be many such mounts depending on the application. I want to achieve that dynamically by defining mount points and volumes in host_vars
-
-
-
"mountPoints": [
{
"readOnly": null,
"containerPath": "/mnt/downloads",
"sourceVolume": "downloads"
}
-

-

-
"volumes": [
{
"efsVolumeConfiguration": {
"transitEncryptionPort": ENABLED,
"fileSystemId": "fs-ecdg222d",
"authorizationConfig": {
"iam": "ENABLED",
"accessPointId": null
},
"transitEncryption": "ENABLED",
"rootDirectory": "/vol/downloads"
},
"name": "downloads",
"host": null,
"dockerVolumeConfiguration": null
}
I am not sure how to do that. Official documentation offers very little help.
