bundle install
# Create ssh key for Github
ssh-keygen -t rsa -b 4096 -C “YOUR EMAIL REGISTERED IN GITHUB”
# Click enter to use default location for key
# You can choose empty passphrase by clicking enter twice
# Now that we have the key, let’s share with Github
less ~/.ssh/id_rsa.pub
# Copy the contents of the id_rsa.pub
- Go to your Github SSH key settings
- Create a new ssh key with title: “docker key”: “PASTE THE KEY CONTENTS HERE”

# Create project dir, assuming your project is `AUTHOR/PROJECT` on GitHub
cd ~/builds \
mkdir AUTHOR \
cd AUTHOR \

# change to the branch or commit you want to investigate
# compile travis script into bash script
travis compile > ci.sh
# Go to bash script and fix the branch name
vi ci.sh
# in Vi type “/branch” to search and add the right branch name
# — branch\=\’\NEW_BRANCH’\
# You most likely will need to edit ci.sh as it ignores ‘matrix’ and ‘env’ keywords
bash ci.sh
