RaspberryPi3B+にJenkins入れるメモ

okuokuokuoku

OSは普通にRaspberry Pi OS Lite。ディスクイメージの書き込み時にSSH host key等が同時投入できて大分便利になった。

apt で導入

これは公式サイト https://www.jenkins.io/doc/book/installing/linux/ 通り。

apt install openjdk-11-jre-headless

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee \
  /usr/share/keyrings/jenkins-keyring.asc > /dev/null
echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins

タイムアウトで起動しない

何かバカみてぇに遅い。。

Job for jenkins.service failed because a timeout was exceeded.
See "systemctl status jenkins.service" and "journalctl -xe" for details.
invoke-rc.d: initscript jenkins, action "start" failed.
● jenkins.service - Jenkins Continuous Integration Server
     Loaded: loaded (/lib/systemd/system/jenkins.service; enabled; vendor preset: enabled)

dpkg: error processing package jenkins (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

とりあえずserviceのファイル /etc/systemd/system/multi-user.target.wants/jenkins.service を直接編集して起動タイムアウトを無限にした。

TimeoutStartSec=infinity

タイムアウトを無限にした後は、サービス自体をリロードする必要がある。

systemctl daemon-reload

systemd未だに慣れないんだよなぁ。。
