How to git without finger print confirmation

In this article i will explain how you can run git clone command on a machine without having to accept sh key finger prints manually.

Lets you want to write a script to initialise a developer machine, which require you to git clone various projects from gitlab or github or any other git repo.

First time you run a git clone command, it will ask you if you accept the signature and it need to be part of automated script, its not nice thing to have.


Here is the solution.

  • First you download the git host's key
  • then create its finger print
  • then check this finger print against known valid finge rprint
  • If its good then move downloaded ssh key to ~/.ssh/known_hosts file
  • else throw error





ssh-keyscan github.com >> githubKey
ssh-keyscan gitlab.com >> gitlabKey


export githubfinger=$(ssh-keygen -lf githubKey)
export gitlabfinger=$(ssh-keygen -lf gitlabKey)


echo $githubfinger
echo $gitlabfinger

if [[ $githubfinger == *"nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8"* ]]; then
  echo "Github Key check succesfull"
  cat githubKey >> ~/.ssh/known_hosts
else
  echo "Github key check failed"
exit 1
fi


if [[ $gitlabfinger == *"ROQFvPThGrW4RuWLoL9tq9I9zJ42fK4XywyRtbOz/EQ"* ]]; then
  echo "Gitlab Key check succesfull"
  cat gitlabKey >> ~/.ssh/known_hosts
else
  echo "Gitlab key check failed"
exit 1
fi




rm -f githubKey
rm -f gitlabKey

There are more things static do behind the screen then things mentioned above. Static fields will not be serialised.
