LGTM

Not 100% sure what this additional rules alias is doing but does this communities one need to be here? looks like the others are for aliasing the previous levellingup domains. This is also the only one that isn't relative to the ${COPILOT_ENVIRONMENT_NAME}

[gidsg]

@sfount Ah, yes, this is v tricksy, it's because we hit the limit of 5 conditions on an ALB listener rule, as we need 6 aliases here, so we need to use the additional_rules to work around this.

This is as per the guidance from the copilot CLI:

You can split the "alias" and "allowed_source_ips" field into separate rules, so that each rule contains up to 5 values: 

http:
  path: /
  alias: [frontend.dev.access-funding.test.levellingup.gov.uk,authenticator.dev.access-funding.test.levellingup.gov.uk,account.access-funding.dev.communities.gov.uk,assess.access-funding.dev.communities.gov.uk]
  allowed_source_ips: []
  additional_rules:
    - path: /
      alias: [apply.access-funding.dev.communities.gov.uk]
      allowed_source_ips: []
✘ validate manifest against environment "dev": validate "http": validate condition values per listener rule: listener rule has more than five conditions 

See also: https://aws.github.io/copilot-cli/docs/manifest/lb-web-service/#http-additional-rules

This is also the only one that isn't relative to the ${COPILOT_ENVIRONMENT_NAME}

Yes, good spot, I can change it to use that variable although it wouldn't make any difference yet as we're only doing it in dev so far.

Also good spot @sfount the apply one there is a typo , will fix now!
