Uninstalling the Ruby data collector

To uninstall the Ruby data collector, roll back the changes that you have made to your application and then update the application deployment.

Procedure

• To uninstall stacktracer-20.06.00.gem from Ruby application in Kubernetes environment, do the following steps:

  1. Remove the following lines in Docker file:

     RUN cp <app_folder>/RubyDC/stacktracer-20.06.00.gem <app_folder>/vendor/cache/
     RUN echo "gem 'stacktracer','=20.06.00'" >> Gemfile
     

  2. Remove stacktracer-20.06.00.gem from the Ruby application folder, for example, rm -f <app_folder>/RubyDC/stacktracer-20.06.00.gem.

  3. Rebuild the application docker image.

     docker build --network=host -t <image-name>:<version>
     

  4. Repush it to a docker repository.

     docker tag <image-name>:<version> <docker-repository>/<namespace>/<image-name>:<version>
     docker push <docker-repository>/<namespace>//<image-name>:<version>
     

  5. Redeploy the application deployment in Kubernetes environment, or relaunch the docker image into container.

• To uninstall the Ruby data collector in on-premises environment, do the following steps:
  1. Run gem uninstall stacktracer.
  2. Remove gem 'stacktracer','=20.06.00' from the Gemfile.
  3. Rerun the Ruby On Rails application by rails s -p 3000 -b 0.0.0.0.
