Exposing a chart in LXD controller does nothing

[sarony11 (Saul Fernandez)]

Hello @pengale, I have been working on this, and I would like to clarify what is happening to me.

I also created this post, just in case could be related in anyhow.

Why deploying charts does not work in micrk8s controller?

Hello community, I am learning and even after reading documentation, I am feeling very lost. Question: deploying charts only works in LXD controller. In microk8s does not work. What can I do? Why is this happening? Listing Controllers, there are two. A microk8s (the one already installed with Ubuntu 20.04) and the LXD Hypervisor for localhost (that I dont know perfectly what it is) Controller Model User Access Cloud/Region Models Nodes HA Version lx…

Question: Using LXD controller, when exposing, I do not make it work (or something I am doing wrong)

Hello Juju!

Here comes the problem.

administrator@master-ubuntu:~$ curl 192.168.2.5
curl: (7) Failed to connect to 192.168.2.5 port 80: Connection refused
administrator@master-ubuntu:~$ curl localhost
curl: (7) Failed to connect to localhost port 80: Connection refused

How can I make this pod available to be exposed from outside?

I am a network administrator and in fact, ingress, networking, domains and certs is the most complicated part in finding on Kubernetes and Juju. If anyone reading can give clear resources about this to learn practically and in deep I would much appreciate.

Thanks for your help,
