# Get the private key used to checkout the private repos from Drone IO environment.
# This key is used to checkout private repos from Github / Bitbucket.
# 1. Create SSH key pair
# 2. Create user on Github / Bitbucket, set the public key for this user, then the let the user access to your private repos
# 3. Export the private SSH key, convert it to a single line entry, lines separated by comma (replace \n with ,)
# In Drone IO project environment variables set the key as  SSH_PRIV_KEY="-----BEGIN RSA PRIVATE KEY-----,...,1TX/Pk9TBggjCvIzWEQfm5W1/VSv9TLt6pVFhORPdYMmCItCtjB49w==,-----END RSA PRIVATE KEY-----".
# You need to separate lines by comma and store the key as single liner, as the Drone IO settings storage gets confused otherwise.
# Example: cat ~/.ssh/key | tr "\n" ","
echo $SSH_PRIV_KEY | tr "," "\n" > /tmp/private-key
chmod o-wrx,g-rwx /tmp/private-key
eval `ssh-agent`
ssh-add /tmp/private-key
