Jenkins Ansible插件找不到可執行文件

Question

我正在Amazon EC2上運行Jenkins-Docker容器中的主服務器和單獨盒子上的代理。 我的劇本使用Jenkins Ansible插件執行Ansible腳本。

我必須在代理上安裝新版本的Ansible。 我使用“ 從源代碼運行”說明從git安裝了Ansible，並將其安裝到/home/ec2-user/ansible. 如果我使用ssh代理，並運行which ansible ~/ansible/bin/ansible按預期方式獲得~/ansible/bin/ansible 。 在“管理Jenkins”>“全局工具配置”頁面上，我在新安裝的“ Ansible可執行文件目錄”中輸入了/home/ec2-user/ansible/bin 。

但是，當我運行Jenkins管道時，得到以下信息：

Running on docker-agent-1 in /home/ec2-user/jenkins/workspace/planet-healthcare-pipeline
[Pipeline] {
[Pipeline] pwd
[Pipeline] stage
[Pipeline] { (Download source and capture commit ID)
[Pipeline] sh
[planet-healthcare-pipeline] Running shell script
+ which ansible
which: no ansible in (/usr/local/bin:/bin:/usr/bin)

它說它正在docker-agent-1 （這是我的代理的名稱）上運行，如果在此ssh可以看到Ansible。 Jenkins為什么找不到Ansible可執行文件？

更新：將PATH添加為環境變量后，它可以找到Ansible，但是現在其他東西壞了。 這是新的輸出：

它的失敗，在“運行測試套件”的階段-它無法找到rails運行rails db:migrate ，即使我知道它在容器中。

為什么在代理上設置PATH會影響Docker容器內發生的腳本？

Answer 1

您在腳本中執行which ansible嗎？ 它僅搜索定義的PATH。
看來/home/ec2-user/ansible/bin不在/usr/local/bin:/bin:/usr/bin （從您的輸出中）。
您可以轉到Jenkins中的agent-node設置，並使用$PATH:/home/ec2-user/ansible/bin值添加PATH環境變量。
