Access from laptop¶
This guide will take you through the required tools and permissions that need to be in place for you to be able to operate your own NAIS application directly from your laptop.
Set up a team¶
The primary unit of access is a team, whose origin lies in NAIS console. Each team is given its own namespace with the same name as the team. The team will have unrestricted access to all Kubernetes assets in that namespace.
See creating a new team to get started with teams. After creating a new team, you should have access to all clusters.
You're probably part of an existing team
If this is your first time here, chances are that you're already part of a team in the context of NAIS. Please speak with your colleagues in order to figure this out. You can also log in to NAIS console and check.
Install naisdevice¶
naisdevice ensures that your laptop meets NAVs requirements before allowing access to internal resources such as our NAIS clusters. Install by following the naisdevice installation guide.
Install kubectl
¶
kubectl
is a command-line tool used to manage your Kubernetes resources.
Check out kubectl´s
official documentation for instructions on how to install the binaries.
Remember that kubectl
is supported within one minor version (older or newer) of kube-apiserver
.
This is called version skew
.
On-prem version is shown in Grafana - clusters.
Using brew
to manage kubectl
will make it troublesome to be within the version skew, as it's hard to downgrade kubectl
to older versions.
Therefor we recommend installing kubectl
manually, or through tools like asdf.
Setup your kubeconfig
¶
The kubectl
tool uses a kubeconfig
file to get the information it needs in order to connect to a cluster.
We provide a pre-made kubeconfig file with NAV's clusters.
Info
If you use utviklerimage
or connect to NAV through BigIP VPN you need to use the kubeconfig under the Git tag utviklerimage
. Go to the directory where you cloned kubeconfig and run
kubectl
will by default look for a file named config
in the $HOME/.kube/
folder. This can be overriden by having the absolute path of the file in the environment variable KUBECONFIG
.
The above example can also be added to something like ~/.bash_profile
, or the equivalent in your preferred shell.
Warning
If you use cygwin, you need the KUBECONFIG
to be in Windows style paths rather than unix style paths (e.g. C:\dev\kubeconfigs\config
instead of /cygdrive/c/dev/kubeconfigs/config
)
Authenticate kubectl
¶
Google Cloud Platform (GCP)¶
Before following these steps, make sure your team is enabled for Google Cloud Platform.
You will also need to perform a self-service step to synchronize your user from Azure AD to Google Cloud Platform. This can be done by following these steps:
- Login to My Apps > Add Application
- Locate "Google Cloud Platform", and click on the icon
After you have done this your user will be synced to Google Cloud Platform. The sync is not instantaneous, but usually does not take more than a few minutes.
First you need to install gcloud
following the instructions for your platform.
Once installed, you need to authenticate with Google using your NAV e-mail.
You will also need to install a plugin in order to authenticate to the Kubernetes clusters:
Then, select a cluster:
And verify that you're connected:
On-premise¶
When connecting to on-premise clusters, you need to authenticate with Azure AD.
$ kubectl config use-context prod-fss
Switched to context "prod-fss".
$ kubectl get pods
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code CR69DPQQZ to authenticate.
When prompted like above, go to the address and enter the code. You then log in with your NAV e-mail and password. When done, kubectl
will update your kubeconfig
-file with the tokens needed to gain access to the cluster.
Recommended tools¶
- kubectx - Simplifies changing cluster and namespace context.
- kubeaware - Visualize which cluster and namespace is currently active.
- Starship - Visualize which cluster and namespace is currently active in your terminal prompt, amongst many other things. Kubernetes specific config
- emacs-kubectx-mode - Switch kubectl context and namespace in Emacs and display current setting in mode line.
