Containers resource requirements

Containers HostAliases Requirements

Sometimes you might need to use HostAliases in web/task containers.

Name	Description	Default
host_aliases	A list of HostAliases	None

Example of customization could be:

---
spec:
  ...
  host_aliases:
    - ip: <name-of-your-ip>
      hostnames:
        - <name-of-your-domain>

Containers Resource Requirements

The resource requirements for both, the task and the web containers are configurable - both the lower end (requests) and the upper end (limits).

Name	Description	Default
web_resource_requirements	Web container resource requirements	requests: {cpu: 100m, memory: 128Mi}
task_resource_requirements	Task container resource requirements	requests: {cpu: 100m, memory: 128Mi}
ee_resource_requirements	EE control plane container resource requirements	requests: {cpu: 50m, memory: 64Mi}
redis_resource_requirements	Redis container resource requirements	requests: {cpu: 100m, memory: 128Mi}
postgres_resource_requirements	Postgres container (and initContainer) resource requirements	requests: {cpu: 10m, memory: 64Mi}
rsyslog_resource_requirements	Rsyslog container resource requirements	requests: {cpu: 100m, memory: 128Mi}
init_container_resource_requirements	Init Container resource requirements	requests: {cpu: 100m, memory: 128Mi}

Example of customization could be:

---

  ...

      memory: 2Gi

Limits and ResourceQuotas

If the cluster you are deploying in has a ResoruceQuota, you will need to configure resource limits for all of the pods deployed in that cluster. This can be done for AWX pods on the AWX spec in the manner shown above.

There is an example you can use in awx_v1beta1_awx_resource_limits.yaml.
