This answer is good https://stackoverflow.com/a/29677091/6135922, but I changed a little bit preinstall script. Hope this will help someone.

#!/bin/bash
# Generates an SSH config file for connections if a config var exists.

echo "Preinstall"

if [ "$GIT_SSH_KEY" != "" ]; then
  echo "Detected SSH key for git. Adding SSH config" >&1
  echo "" >&1

  # Ensure we have an ssh folder
  if [ ! -d ~/.ssh ]; then
    mkdir -p ~/.ssh
    chmod 700 ~/.ssh
  fi

  # Load the private key into a file.
  echo $GIT_SSH_KEY | base64 --decode > ~/.ssh/deploy_key

  # Change the permissions on the file to
  # be read-only for this user.
  chmod o-w ~/
  chmod 700 ~/.ssh
  chmod 600 ~/.ssh/deploy_key

  # Setup the ssh config file.
  echo -e "Host bitbucket.org\n"\
          " IdentityFile ~/.ssh/deploy_key\n"\
          " HostName bitbucket.org\n" \
          " IdentitiesOnly yes\n"\
          " UserKnownHostsFile=/dev/null\n"\
          " StrictHostKeyChecking no"\
          > ~/.ssh/config

  echo "eval `ssh-agent -s`"
  eval `ssh-agent -s`

  echo "ssh-add -l"
  ssh-add -l

  echo "ssh-add ~/.ssh/deploy_key"
  ssh-add ~/.ssh/deploy_key

  # uncomment to check that everything works just fine
  # ssh -v git@bitbucket.org
fi
