Travis CI

One of the original hosted CI/CD systems.

Reasonable UI, but...

travis-ci.org was free for open source, but has been retired.

travis-ci.com remains as a paid offering.

This has caused Travis CI to go from once leading open source to now legacy CI/CD.

Superceded by newer more free CI/CD systems like GitHub Actions now which is unlimited free for all public projects.

Travis CI Template

Copy to root of GitHub repo and edit:

.travis.yml

Online Config Validator

Paste .travis.yml config in this online validator to see parsing and job matrix:

https://config.travis-ci.com/explore

Desktop Menu Notifications

• CCMenu - Mac OSX menu watcher
• BuildNotify - for Linux

Travis CI URL for monitoring a Repo

Here is the URL for the above desktop notifiation tools

https://api.travis-ci.org/repos/<owner>/<repo>/cc.xml

Returns empty json {} if it doesn't find the repo

Config I used for CCMenu on Mac for several years to monitor my GitHub repos:

CCMenu.plist

Travis CI CLI

Follow the install doc or paste this to run an automated install script which auto-detects and handles Mac or Linux:

git clone https://github.com/HariSekhon/DevOps-Bash-tools

bash-tools/install/install_travis.sh

OR manually:

gem install travis --no-rdoc --no-ri

travis login

travis token

CLI Usage

Linting:

travis lint  # .travis.yml

Switches of notes:

Switch	Description
-q	quiet mode
-x	exit 1 if lint fails

travis lint -x .travis.yml

travis endpoint --org --set-default

travis login

Set up this token in github:

travis login --github-token

Set up token in .netrc:

travis login --auto

travis monitor -r <repo1> -r <repo2>

Switch	Description
-n	all my repos
-m	notify desktop

Left hand pan recent repo statuses:

travis whatsup

travis history

Create .travis.yml template for given lang:

travis init <lang>

travis init java

Restart Travis CI build from within a Git repo checkout:

travis restart

Make sure it is case sensitive otherwise you'll get output:

repository not known to https://api.travis-ci.org/: harisekhon/nagios-plugins

in local checkout's .git/config:

[travis]
    slug = HariSekhon/nagios-plugins

Docker

Travis hosts containers on Quay.io

• port 22
• login:
  • user: travis
  • password: travis

Supported for the following languages:

• android
• erlang
• go
• haskell
• jvm
• node-js
• perl
• php
• python
• ruby

Hangs so don't run in foreground:

docker run -d -p 2222; 22 --name travis-${TRAVIS_LANGUAGE} quay.io/travisci/travis-${TRAVIS_LANGUAGE}

ssh -p 2222 travis@$HOST # pw travis

or

docker exec travis-${TRAVIS_LANGUAGE}
su - travis

Troubleshooting

Launch a debug VM

Username + Password for GitHub:

travis login --org --auto
travis token --org

This should be the last bit of the url, eg.

https://travis-ci.org/HariSekhon/nagios-plugin-kafka/jobs/144678953

means

JOB_ID=144678953
export JOB_ID

export TRAVIS_TOKEN=$(travis token --org | awk '{print $2}')

echo "Travis token is $TRAVIS_TOKEN"

curl -s -X POST -H "Content-Type: application/json" -H "Accept: application/json" -H "Travis-API-Version: 3" -H "Authorization: token $TRAVIS_TOKEN" "https://api.travis-ci.org/job/$JOB_ID/debug"

travis_debug() in .bash.d/travis_ci.sh

In Web UI log, see lines

Setting up debug tools.
Preparing debug sessions.
Use the following SSH command to access the interactive debugging environment:
ssh <login_token>@ny2.tmate.io

SSH to the given address on the last line.

Debug Automation

From DevOps-Python-tools repo:

• travis_debug_session.py
  • automates creating a Travis CI interactive debug build session via the Travis API
  • tracks the creation of the debug build, parses the log and drops you in to the unique SSH shell login as soon as it's available
• travis_last_log.py
  • automates fetching the last running / completed / failed build log from Travis CI via the Travis API
