[Bug]: Jenkinsfile docker stage requires an agent but agent is none

[kavilla]

Describe the bug

The detect Docker image + args to use for the build stage for the OpenSearch and OpenSearch Dashboards Jenkinsfile throws this error:

Required context class hudson.FilePath is missing Perhaps you forgot to surround the code with a step that provides this, such as: node
--
Error signal | Attempted to execute a step that  requires a node context while ‘agent none’ was specified. Be sure to  specify your own ‘node { ... }’ blocks when using ‘agent none’.

The agent is none for the pipeline so each stage would have to define there on agent if they are doing work.

To reproduce

Run https://github.com/opensearch-project/opensearch-build/blob/main/jenkins/opensearch-dashboards/Jenkinsfile through Jenkins and see error.

Expected behavior

For it to build.

Additional context

Should we just throw

agent {
      docker {
          label 'Jenkins-Agent-al2-x64-c54xlarge-Docker-Host'
          image 'opensearchstaging/ci-runner:centos7-x64-arm64-jdk14-node10.24.1-cypress6.9.1-20211005'
          alwaysPull true
      }
}

into that stage? Or just create an agent that can does the work of pulling that value from the manifest.yaml file.
