With regard to the error you’re getting, either the key is wrong or the validator username is wrong. You may have a chef user with the same client name as this node. If you have some more points to add you can do that but make sure the above the above explanation is there in your answer.
- In the later stages, more specific DevOps interview questions for experienced candidates can be used to test skills.
- When done with care, this will allow the feature branch to be merged into master with relative ease and sometimes as a simple fast-forward operation.
- The CI server monitors the repository and checks out changes when they occur.
- Hello guys, if you re preparing for DevOps Engineer interviews and looking for frequently asked DevOps Interview questions then you have come to the right place.
