# demo-helm
|
|
|
|
A demo helm chart to deploy a simple web app written in Python.
|
|
|
|
## Build and push the sample app image
|
|
|
|
Use the `Makefile` to build and push the image.
|
|
|
|
```
|
|
make push-app-image
|
|
```
|
|
|
|
## Helm install/upgrade
|
|
|
|
### New Deployments
|
|
|
|
```
|
|
helm install <NAME> charts/demo-helm
|
|
OR
|
|
helm install charts/demo-helm --generate-name
|
|
```
|
|
|
|
### Upgrading Deployments
|
|
|
|
Get your deployment ID
|
|
```
|
|
helm list
|
|
```
|
|
|
|
```
|
|
helm upgrade demo-helm-1633825301 charts/demo-helm
|
|
```
|
|
|
|
You can wait for successful deployment too.
|
|
|
|
```
|
|
helm upgrade demo-helm-1633825301 charts/demo-helm --wait
|
|
```

## Setting registry pull secrets
|
|
|
|
You have to have an image pull secret. So first you need the secrets:
|
|
|
|
From: [The k8s docs]
|
|
|
|
```
|
|
kubectl create secret docker-registry regcred \
|
|
--docker-server=https://registry.runcible.io \
|
|
--docker-username=<your-name> \
|
|
--docker-password=<your-pword> \
|
|
--docker-email=<your-email>
|
|
```
|
|
|
|
Then you need to specify the secret in your deployment spec like so:
|
|
|
|
```
|
|
spec:
|
|
containers:
|
|
- image: registry.runcible.io/demo-helm:1.0.1
|
|
imagePullPolicy: Always
|
|
name: backend
|
|
ports:
|
|
- name: backend
|
|
containerPort: 5000
|
|
imagePullSecrets:
|
|
- name: regcred
|
|
```
|
|
|
|
## Creating the Database password as a secret
|
|
|
|
```
|
|
kubectl -n <your namespace> create secret generic database_secret \
|
|
--from-literal=password=<your secret>
|
|
```
|
|
|
|
