"Host key verification failed" when deploying Dockerfile app in RHOCP 4

Solution Verified - Updated -


  • When attempting to deploy a Spring Boot application using a Dockerfile, encountered an error, Host key verification failed, while trying to clone the code using the provided SSH files in the Dockerfile.
  • The used Dockerfile used:
// Installing git
  FROM image-registry.openshift-image-registry.svc:5000/openshift-xxx-streams/xyz
// Add ssh private key into the container
  RUN mkdir ~/.ssh/
  COPY ./id_rsa  ~/.ssh/
  RUN echo -e "StrictHostKeyChecking no" >> ~/.ssh/id_rsa
  RUN chmod 600 ~/.ssh/id_rsa
// clone the container
  RUN git clone ssh://git@bitbucket.xxx.xx.x:7999/xxx/xyz.git &&   git clone ssh://git@bitbucket.xxx.xx.x:7999/xxx/xyz.git

While executing the above Dockerfile, getting the error below:

"Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists."
