Overview
This charm is intended to be used with Juju's Getting Started documentation.
Usage
Deploying hello-juju
:
juju deploy hello-juju
juju expose hello-juju
You can now access the application by connecting to the unit's public address field from the juju status
output:
juju status
> ...
> App Version Status Scale Charm Store Rev OS Notes
> hello-juju active 1 hello-juju local 0 ubuntu exposed
>
> Unit Workload Agent Machine Public address Ports Message
> hello-juju/0* active idle 0 <ip-address> 80/tcp
>
> Machine State DNS Inst id Series AZ Message
> 0 started <ip-address> <instance-id> bionic Running
Now from another computer, you'll be able to make HTTP requests to it.
curl <ip-address>
> Hello Juju!
If you don't have curl
, open your browser at <ip-address>
.
The charm also installs curl
on hello-juju/0
, so you could try that too.
juju ssh hello-juju/0
> ubuntu@<instance-id>:~$
curl localhost
> Hello Juju!
