[英]Jenkins unable to create directory '/var/lib/jenkins/.ssh' when ssh into EC2
問題:在我的 Jenkins 過程中,我能夠與我想將文件復制到的 EC2 實例建立連接,但我不斷收到以下錯誤:
Could not create directory '/var/lib/jenkins/.ssh'
Failed to add the host to the list of known hosts (/var/lib/jenkins/.ssh/known_hosts).
和
Host key verification failed.
背景:在我將代碼推送到“master”分支后,我的 Jenkins 工作由 github webhook 觸發。 Jenkins 讀取存儲庫的 Jenkinsfile 並創建一個 Docker 代理來構建應用程序,然后將構建的文件部署到 EC2 容器。 在部署階段,我使用 Jenkin 的 sshagent 建立連接,然后使用命令刪除舊文件,然后將新文件復制到 EC2。
pipeline {
agent {
docker {
image 'node:buster'
args '-p 20001-20100:3000'
args '-v /etc/passwd:/etc/passwd'
}
}
environment {
CI = 'true'
HOME = '.'
npm_config_cache = 'npm-cache'
}
stages {
stage('Install') {
...install code... <<<<<<<[works, no issues]
stage('Build') {
...build code... <<<<<<<[works, no issues]
}
stage('Deploy') {
parallel {
stage('Deploy frontend') {
...deploy frontend code to S3 bucket... <<<<<<<[works, no issues]
}
stage('Deploy backend') {
steps {
dir('backend') {
sshagent(['code_commit_key']) {
sh 'ssh -o StrictHostKeyChecking=no ec2-user@ecx-xx-xx-x-xx.compute-1.amazonaws.com "whoami"' <<<<<[this return ec2-user after list of errors]
sh 'ssh -o StrictHostKeyChecking=no ec2-user@ecx-xx-xx-x-xx.compute-1.amazonaws.com "sudo su -; pm2 delete -s order-form-nestjs; rm -rf ./dist"' <<<<<[this returns list of errors]
sh 'scp -r ./dist/* ec2-user@ecx-xx-xx-x-xx.compute-1.amazonaws.com:/home/ec2-user' [this returns list of errors]
sh 'ssh -o StrictHostKeyChecking=no ec2-user@ecx-xx-xx-x-xx.compute-1.amazonaws.com "sudo su -; pm2 start dist/main.js --name=backend-app-nestjs"' <<<<<[this returns list of errors]
echo 'Ssh successful'
}
}
}
}
}
}
}
}```
你可以從你的 jenkins 服務器 ssh 你的 EC2s 嗎? 你能檢查一下嗎
在這里找到我的答案:
默認情況下,當未指定用戶時,docker 使用在 dockerfile 中定義的用戶啟動 [原文如此] 容器,如果未指定,則為 root。
我將args '-u root:root -v /var/lib/jenkins/workspace/myworkspace:/tmp/' + ' -v /var/lib/jenkins/.ssh:/root/.ssh'
到我的 docker 代理代碼和中提琴,成功!:
agent {
docker {
image 'node:buster'
args '-p 20001-20100:3000'
args '-v /etc/passwd:/etc/passwd -v /etc/group:/etc/group'
args '-u root:root -v /var/lib/jenkins/workspace/myworkspace:/tmp/' + ' -v /var/lib/jenkins/.ssh:/root/.ssh'
}
}
