Nomad (HashiCorp)

Configuration

TLS support

When Nomad is configured to use TLS, the sensor requires access to the CA certificate, the client certificate, and the client private key to collect performance metrics. To configure access to these files, edit the agent configuration file (/opt/instana/agent/etc/instana/configuration.yaml):

com.instana.plugin.nomad:
  caCertificate: '' # path to CA certificate *.pem file (eg. /etc/nomad/ca-cert.pem)
  clientCertificate: '' # path to client certificate *.pem file (eg. /etc/nomad/client-cert.pem)
  clientKey: '' # path to client private key *.pem file (eg. /etc/nomad/client-key.pem)
