Can't use dep/glide packages from docker file task in azure devops to build images from other repos. Host Key Verifiaction failed error - azure-devops

Question

I'm trying to use docker container task in azure DevOps pipeline to build and push images to ACR and ECR. I am able to do that through a YAML file and automate all the processes but when I am trying the same with a docker file which has dep and glide packages to fetch from other repos both from public GitHub repos and private bitbucket repos. It fails with the Host Key Verification error. The same dockerfile works with Jenkins but I don't know how to solve this ssh-key error on a Hosted Ubuntu Agent.

The above file is the dependency repos that are to be fetched using glide.yml file.

Answer 1

I fixed it finally, what I needed was a service account which has read access to all the repos that glide is trying to access. Read access was required for all those repos with a Bitbucket Service Connection in Azure Pipeline. The error is not specific to glide, it is more inclined with the git repo access.
