sudo snap install microk8s --classic --channel=1.18/stable sudo snap refresh microk8s --classic --channel=1.19/stable Or (when the master node bug will be fixed on 1.19 kubernetes snap install) sudo snap install microk8s --classic --channel=1.19/stable |
You may need to change your firewall configuration to allow pod to pod communication and pod to internet communication :
...
Storage addon : we will enable the default Host storage class, this allows local volume storage that are used by some pods to exchange folders between containers.
| Code Block |

sudo microk8s enable dns storage |

sudo snap install helm --classic --channel=3.5/stable |
3) Tweak Microk8s
Note: You may encounter some log issues when installing helm with snap
Normally the helm logs are available in "~/.local/share/helm/plugins/deploy/cache/onap/logs", if you notice that the log files are all equal to 0, you can uninstall the helm with snap and reinstall it manually
| Code Block |
|---|
wget https://get.helm.sh/helm-v3.5.4-linux-amd64.tar.gz
|
| Code Block |
|---|
tar xvfz helm-v3.5.4-linux-amd64.tar.gz
|
| Code Block |
|---|
sudo mv linux-amd64/helm /usr/local/bin/helm
|
3) Tweak Microk8s
The below tweaks are not strictly necessary, but they help in making the setup more simple and flexible.
A) Increase the max number of pods & Add priviledged config
As ONAP may deploy a significant amount of pods, we need to inform kubelet to allow more than the basic configuration (as we plan an all in box setup), if you only plan to run a limited number of components, this is not needed
to change the max number of pods, we need to add a parameter to the startup line of kubeletedit parameter to the startup line of kubelet.
1. Edit the file located at :
| Code Block |
|---|
sudo nano /var/snap/microk8s/current/args/kubelet |
add the following line at the end :
| Code Block |
|---|
--max-pods=250 |
save the file and restart kubelet to apply the change :
| Code Block |
|---|
sudo service snap.microk8s.daemon-kubelet restart |
2. Edit the file located at :
| Code Block |
|---|
sudo nano /var/snap/microk8s/current/args/kubeletkube-apiserver |
add the following line at the end :
| Code Block |
|---|
--maxallow-podsprivileged=250true |
save the file and restart kubelet to apply the change :
| Code Block |
|---|
sudo service snap.microk8s.daemon-kubeletapiserver restart |
B) run a local copy of kubectl
Microk8s comes bundled with kubectl, you can interact with it by doing:
| Code Block |
|---|
sudo microk8s kubectl describe node |
...
| Code Block |
|---|
cd
mkdir .kube
cd .kube
sudo microk8s.config > config
chmod 700 config |
...
the example below pulls the latest version from master, it's probably wiser to select the right version (honolulu branch or a specific review you want to test)
| Code Block |
|---|
cd
git clone --recursive "https://gerrit.onap.org/r/oom" |
...
| Code Block |
|---|
helm plugin install --version v0.9.0 https://github.com/chartmuseum/helm-push.git |
...
unless you already have docker, in which case you can skip this part altogether.
Or use snap:
| Code Block |
|---|
sudo snap install docker |
8) Build all oom charts and store them in the chart repo
You should be ready to build all helm charts, go into the oom/kubernetes folder and run a full makefull make
Ensure you have "make" installed:
| Code Block |
|---|
sudo apt install make |
Then build OOM
| Code Block |
|---|
cd ~/oom/kubernetes make all |
