aws elb #17

Supports: bionic

Add to new model

Description

This layer provides the AWS-ELB.


layer-aws-elb

This layer adds AWS ElasticLoadBalancer infront of your EC2 deployed applications.

Usage and Caveats

To use this charm you must have a pre-existing ACM cert
for the domain/fqdn you wish to use on the ELB, as well as pre-existing IGW subnets.

Future version of this charm will offer lets-encrypt cert creation/acquisition capability.

Deployment Example

```bash

Create the model and network space

(I often use a "nat" space that includes subnets that use a routing table that points 0.0.0.0/0 -> nat-gw)

juju add-model aws-elb-testing aws/us-west-2
juju add-spaces nat 172.31.102.0/24 172.31.103.0/24 172.31.104.0/24
bash

Deploy the 2 primary charms and the subordinate

juju deploy cs:~containers/aws-integrator-5 --constraints "spaces=nat instance-type=m5.large"

juju deploy cs:~omnivector/aws-elb-16

juju deploy cs:~jamesbeedy/flask-test-2 --constraints "spaces=nat instance-type=m5.large"
juju expose flask-test

Trust, config, and make relations

(The aws-elb charm will block until the 'subnets' and 'cert-fqdn' configs are set)

juju trust aws-integrator

(use your own cert-fqdn and subnet ids - both must pre-exist in aws)

juju config aws-elb cert-fqdn="*.peopledatalabs.com"
juju config aws-elb subnets="subnet-1de11955,subnet-50b0f336,subnet-7128282a"

juju relate aws-integrator aws-elb

juju relate aws-elb flask-test
`` After the ELB is [successfully created](https://paste.ubuntu.com/p/QzMS6fW8XK/), you can use the actionget-elb-dns` to get the dns name of the ELB.

bash $ juju run-action aws-elb/17 --wait get-elb-dns unit-aws-elb-17: id: 6e867463-2f3b-4411-82c9-6f14b6b8f209 results: elb-dns: juju-elb-a9dce8c-805899264.us-west-2.elb.amazonaws.com status: completed timing: completed: 2018-09-23 00:48:21 +0000 UTC enqueued: 2018-09-23 00:48:21 +0000 UTC started: 2018-09-23 00:48:21 +0000 UTC unit: aws-elb/17

Following this you need to create/update an CNAME record to point at the FQDN of the ELB before you will be able to successfully access the web endpoint.
