snappass-test

This is a test charm for Pinterest's SnapPass that uses the Python Operator Framework and K8s sidecar containers with Pebble.

Deploying

Before deploying the charm, make sure you have a MicroK8s environment bootstrapped, and add a model:

$ juju bootstrap microk8s
Creating Juju controller "microk8s-localhost" on microk8s/localhost
...
$ juju add-model snappass
Added 'snappass' model on microk8s/localhost with credential 'microk8s' for user 'admin'

You can now deploy the charm directly from Charmhub (you must be using Juju 2.9-rc11 or later):

$ juju deploy snappass-test
Located charm "snappass-test" in charm-hub, revision 9
Deploying "snappass-test" from charm-hub charm "snappass-test", revision 9 in channel stable

After a while juju status should say something like this and (after a few seconds) give you an IP address:

$ juju status
Model     Controller          Cloud/Region        Version   SLA          Timestamp
snappass  microk8s-localhost  microk8s/localhost  2.9-rc12  unsupported  12:07:29+12:00

Visit that IP address at port 5000 in your browser and you should see the SnapPass web UI. For example, http://10.1.147.97:5000/
