这是将您的配置映射打包到 Helm Chart 中的分步说明

#!/bin/bash

# Step 1: Create a new Helm chart
helm create mychart

# Step 2: Add the ConfigMap to the Helm chart
cat <<EOF > mychart/templates/configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: my-configmap
data:
  key1: value1
  key2: value2
EOF

# Step 3: Package the Helm chart
cd mychart
helm package .
cd ..

# Step 4: Generate the Helm install script
cat <<EOF > install_mychart.sh
#!/bin/bash

# Variables
RELEASE_NAME=myrelease
NAMESPACE=mynamespace
CHART=mychart-0.1.0.tgz

# Create namespace if it doesn't exist
kubectl create namespace \$NAMESPACE || true

# Install the Helm chart
helm install \$RELEASE_NAME \$CHART --namespace \$NAMESPACE
EOF

# Make the script executable
chmod +x install_mychart.sh

# Step 5: Run the install script (optional)
# ./install_mychart.sh
