我想在 Jenkins 管道中执行这些步骤：
来自终端或 bash 脚本的初始工作代码是：
// Retrieving the CT list in the VMID range 901 --> 999
VMID_LIST=$(curl --insecure --silent --cookie "$(<~/PVE_API/cookie)" -X GET https://my-proxmox:8006/api2/json/nodes/my-node/lxc | jq '.' | grep vmid | sort | cut -d'"' -f4 | grep "9[0-9][0-9]")
// Determine the first available integer
for i in $(seq 901 999)
do
if ! echo "$VMID_LIST" | grep $i
then
CT_VMID=$i
break
fi
done
// Creating my proxmox container
curl command...
当我在某些步骤中尝试执行 sh/bash 命令时，很多时候它都失败了...
我创建了一个小管道来解释我的错误。
pipeline {
agent { label 'master' }
stages {
stage("Create container") {
steps {
script {
SEQ = sh(returnStdout: true, script: 'seq 1 9').trim()
sh "echo '${SEQ}'"
CTID = sh(returnStdout: true, script: "for id in '${SEQ}'; do echo $id; done").trim()
sh "echo '${CTID}'"
}
}
}
}
}
如果我使用三重双引号，结果相同：
pipeline {
agent { label 'master' }
stages {
stage("Create container") {
steps {
script {
SEQ = sh(returnStdout: true, script: 'seq 1 9').trim()
sh "echo '${SEQ}'"
sh """
for id in '{$SEQ}'
do
echo $id
done
"""
}
}
}
}
}
结果：

如何按预期在 Jenkins 步骤中运行 sh/bash 脚本？
在 Jenkins 管道中执行所有检查或 linux 本机命令的最佳实践是什么？
为什么 Jenkins 提供了一种使用 sh/bash 命令的方法，而其中许多命令没有按预期工作？
Jenkins 专家如何做与我想做的事情类似的事情？
答案 0 :(得分：0)
您需要将 $id 转义为 \$id，否则 Jenkins 会认为您正在尝试使用 Groovy var 而不是 shell var。
即
pipeline {
agent { label 'master' }
stages {
stage("Create container") {
steps {
script {
SEQ = sh(returnStdout: true, script: 'seq 1 9').trim()
sh "echo '${SEQ}'"
sh """
for id in '{$SEQ}'
do
echo \$id
done
"""
}
}
}
}
}
会给你

[Pipeline] { (Create container)

[Pipeline] {
[Pipeline] sh

[Pipeline] }
[Pipeline] // stage
[Pipeline] }

您可能遇到的另一个问题是 seq 在它打印的每个数字后添加一个换行符，因此您的 for 循环将无法工作，因为它需要空格分隔值而不是换行符，因此需要修复您的示例按您的预期工作。
