Deploy existing app to a Kubernetes cluster

Your myUberApp application, bootstrapped with iio, has a Kubernetes deploy configuration file that you can find in the myUberApp/k8s/deploy folder.

# IIOS deploy configuration file apiVersion
apiVersion: 1
# registries to use for image pull (referenced in the app config section)
registries:
  # reference name (use JSON path to query info)
  GitLab:
    # name of the registry domain (think docker login <domain>)
    domain: registry.gitlab.com/
    # configuration data for credentials: here uses a file content
    configData: "{{filedata(~/.docker/config.json)}}"
  # use no registry when local or Docker Hub images
  Local:
    domain: ""
# IIOS app and services section
iios:
  # app section
  app:
    # app image version; here gets from app's package.json file
    version: "{{packageJSON.version}}"
    # use private registry if necessary (prod deploy)
    # registry: "{{$.registries.GitLab}}"
    # this config example uses no registry, so either Docker Hup or local images
    # (ex: deployment made with minikube)
    registry: "{{$.registries.Local}}"
    # app image pull policy
    imagePullPolicy: IfNotPresent

# global cluster configuration
cluster:

  # secrets to be created
  secrets:
    # declare app-secrets (no other reference to the name) that is an YAML file
    # to apply to the cluster
    # WARINING: you must provide this file
    - name: app-secrets
      file: ~/data/app-secrets.yaml
  # ingress to use nginx|traefik. Default nginx
  ingress: nginx
  # path for the kube config file. This allows you to address any Kubernetes cluster
  # WARNING: kubectl must be installed on your machine
  kubeConfigPath: ~/.kube/config

Secrets file (here ~/data/app-secrets.yaml) must be provided. It has to be similar to the following:

apiVersion: v1
kind: Secret
metadata:
  name: iiosecrets
type: Opaque
data:
  emailer_smtp_pass: <base64_string>
  mongodb_pwd: <base64_string>
  s3_access_key_id: <base64_string>
  s3_secret_access_key: <base64_string>

To deploy the full app:

...
# cd to app folder or use -w option to define working directory
cd myUberApp
iio app deploy

Delete exsiting deployment

# you must be in the app folder or use -w option to define working directory
iio app remove

Create a new Ignitial.io service from scratch

iio service create myUberService
