Deploy backend in kubernetes

Follow instructions in the deploying SkyWalking backend to Kubernetes cluster to deploy oap and ui to a kubernetes cluster.

Deploy SkyWalking with local files

Package the corresponding version of the skywalking chart

1.Configure the helm environment, refer to Helm environment configuration. If you want to deploy the helm2 related chart, you can directly configure the relevant environment of helm2. The following example uses the Helm 3 environment.

2.Clone/download ZIP skywalking-kubernetes repo, the directory structure of the repo about chart is as follows

helm-chart

  • helm2
    • 6.0.0-GA
    • 6.1.0
  • helm3
    • 6.3.0
    • 6.4.0

After the clone/download ZIP is completed, enter the specified directory and package the corresponding version of the chart.

cd skywalking-kubernetes/helm-chart/<helm-version>/<skywalking-version>

Note: helm-version is the corresponding helm version directory, skywalking-version is the corresponding skywalking version directory, and below is helm3 and skywalking 6.3.0.

cd skywalking-kubernetes/helm-chart/helm3/6.3.0

3.Since skywalking relies on elasticsearch as storage, execute the following command to update dependencies, which will be pulled from the official repo by default.

helm dep up skywalking
