Only Push Specific Files

odo uses the odo.dev.push.path related attribute from the devfile's run commands to push only the specified files and folders to the component.

The format of the attribute is "odo.dev.push.path:<local_relative_path>": "<remote_relative_path>". We can mention multiple such attributes in the run command's attributes section.

commands:
  - id: dev-run
    attributes:
      "dev.odo.push.path:target/quarkus-app": "remote-target/quarkus-app"
      "dev.odo.push.path:README.txt": "docs/README.txt"
    exec:
      component: tools
      commandLine: "java -jar remote-target/quarkus-app/quarkus-run.jar -Dquarkus.http.host=0.0.0.0"
      hotReloadCapable: true
      group:
        kind: run
        isDefault: true
      workingDir: $PROJECTS_ROOT
  - id: dev-debug
    exec:
      component: tools
      commandLine: "java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=${DEBUG_PORT},suspend=n -jar remote-target/quarkus-app/quarkus-run.jar -Dquarkus.http.host=0.0.0.0"
      hotReloadCapable: true
      group:
        kind: debug
        isDefault: true
      workingDir: $PROJECTS_ROOT

In the above example the contents of the quarkus-app folder, which is inside the target folder, will be pushed to the remote location of remote-target/quarkus-app and the file README.txt will be pushed to doc/README.txt. The local path is relative to the component's local folder. The remote location is relative to the folder containing the component's source code inside the container.
