Add on: Portainer

General Discussions microk8s

Homepage: https://www.portainer.io/
From MicroK8s version: 1.20+
Supported arch: amd64, arm64

Portainer allows you to “build, manage and deploy containers in your Kubernetes environment quickly and easily. No more CLI, no more YAML, no more Kubernetes manifests. Just simple, fast, K8s configuration in a graphical UI, built on a trusted open source platform.”

To enable the addon:

microk8s enable portainer

You will now find the Portainer exposed as a Nodeport http service on port 30777 and as an https service on port 30779. To access it remember to use the IP address or FQDN of the node MicroK8s is running on. Use localhost if you are deploying Portainer on your local workstation.

When first navigating to the URLs above, you will be asked to create a user:

771×554 28.2 KB

Confirm the username and an 8+ character password to continue to the dashboard. This will initially open on the settings page:

1087×738 102 KB

For details of the settings and usage of portainer, see the official documentation

Disabling

The addon can be disabled at any time with the command:

microk8s disable portainer
2

$ microk8s enable portainer
Nothing to do for portainer

Where is the plugin on fresh system?

Sorry portainer isn’t working for you. Some things to check:

  • is MicroK8s the latest version ( snap info microk8s -> v1.20.0 (1864) 219MB classic
  • are you running on something other than amd64?
  • are you set to the 1.20 track? sudo snap refresh microk8s --channel=1.20

Thank you very much!

Hi,
The URL could be 127.0.0.1:30777 with v1.20/stable on Ubuntu Server 20.04.

microk8s.kubectl get all -n portainer

When you visit the portainer URL, do you get a list of API interfaces, or a UI?

I’ve yet to work out how to land on the UI.

N00b advice needed:
The microK8S instance sits behind a firewall that has only 443 and 22 open, so I can’t access Port 30777 or 9000. My understanding is, I could remedy that with an ingress definition pointing to the Portainer service. How would I design that ingress? I’m especially confused about what path to pick.

My first draft:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: first-try
  labels:
    name: demo
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
  rules:
  - host: my.web.site
    http:
      paths:
      - pathType: Prefix
        path: "/portainer"
        backend:
          service:
            name: portainer
            port:
              number: 30777          
  tls:
  - hosts:
    - my.web.page
   secretName: letsencrypt-cert

Deploy this to the default namespace? There are more services that use ingress.
Help is very much appreciated

The ingress must be on the same namespace as the portainer Service.
Try first with the root context / in the path.

@balchua1 Thx for chipping in. So you would suggest:

    paths:
    - pathType: Prefix
      path: "/"

Clashes with the landing page, but I shall try.

Sorry i misunderstood your issue.
As i normally do is to setup a domain name like portainer.local, and configure ingress to route using the host rather than path. I find this easier rather than play with the path prefix.

I am using this addon on Windows 10 using Hyper-V in which case the default URL listed for portainer is not the valid one for me as microk8s is not on localhost but on the VM inside my Hyper-V. In this case I need to run the portainer using Node’s IP address rather than localhost:

Thanks for enabling portainer through microk8s!

I had a question on upgrading, I’m getting a notice in the bottom right of portainer that there is a new version available. Is there any way to upgrade portainer when installed through microk8s?

I would be glad to add this to the docs if someone could point me to any resources.

16

I haven’t tried this yet, but I imagine it can be upgraded per the instructions on the portainer site?

microk8s kubectl apply -n portainer -f https://raw.githubusercontent.com/portainer/k8s/master/deploy/manifests/portainer/portainer.yaml

@kjackal, I’d like to make some changes to the Portainer MicroK8s addon.
However, I don’t think I have enough reputation on discuss.kubernetes.io to make changes.
Also, I see there are some ‘page version 11’ changes there which someone has made and which it would be good to also include before I make new changes.
I want to add command line parameters and update some of the info.
I’m a PO at Portainer.

Hi @jamest-portainer. Could you send me the changes you need here or on an email so I can apply them? Thanks.
