Deploy Examples

Most of the examples below show shortened commands for convenience. The ‘…’ in these examples represents the image references. Be sure to include the image references when running the deploy command.

Deploy the latest version of NGINX Service Mesh, using default values, from your container registry:

nginx-meshctl deploy --registry-server "registry:5000"
Deploy the Service Mesh in namespace “my-namespace”:

nginx-meshctl deploy ... --namespace my-namespace
Deploy the Service Mesh with mTLS turned off:

nginx-meshctl deploy ... --mtls-mode off
Deploy the Service Mesh and enable telemetry traces to be exported to your OTLP gRPC collector running in your Kubernetes cluster:

nginx-meshctl deploy ... --telemetry-exporters "type=otlp,host=otel-collector.my-namespace.svc.cluster.local,port=4317"
Deploy the Service Mesh with upstream certificates and keys for mTLS:

nginx-meshctl deploy ... --mtls-upstream-ca-conf="disk.yaml"

nginx-meshctl inject < ./my-app.json > ./my-injected-app.json
Inject the resources in my-app.yaml and configure proxies to ignore ports 1433 and 1434 for outgoing traffic:

nginx-meshctl inject --ignore-outgoing-ports 1433,1434 -f ./my-app.yaml
Inject the resources passed into stdin and configure proxies to ignore port 1433 for incoming traffic:
