Question

我正在使用最新的Jenkins图像（2.60.3），然后我想更新jenkins.war中的/usr/share/jenkins/jenkins.war文件，以获取最新版本的图像（2.73） 0.3）。我正在尝试使用以下dockerfile来实现它：

FROM jenkins:latest
COPY jenkins.war /usr/share/jenkins/

我将jenkins.war文件放在与dockerfile相同的文件夹中。我遇到的问题是由于某种原因文件没有被覆盖（有jenkins.war v2.60.3）。为什么会发生这种情况？

如评论所述，使用jenkins/jenkins image，我（使用latest LTS）：

FROM jenkins/jenkins:2.73.3

ARG http_proxy
ARG https_proxy

# Skip setup wizard
ENV JAVA_OPTS="-Djenkins.install.runSetupWizard=false"

USER root
RUN addgroup --system --gid 581 dtpdkr && \
    adduser jenkins dtpdkr
USER jenkins

# Remove executors in master
COPY master-executors.groovy /usr/share/jenkins/ref/init.groovy.d/
# Set proxy based on proxy-password secret
COPY set-proxy.groovy /usr/share/jenkins/ref/init.groovy.d/
# Create admin based on secrets jenkins-adm-name and jenkins-adm-pass
COPY security.groovy /usr/share/jenkins/ref/init.groovy.d/security.groovy

# Install plugins
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

这确实为我提供了一个已安装的Jenkins LTS图像，以及我需要的所有插件。

由于我在代理之后，我必须先配置它：

$ more set-proxy.groovy

import hudson.model.*;
import jenkins.model.*;

def instance = Jenkins.getInstance()

final String name = "proxy.mycompany.com"
final int port = 8080
final String username = "unix_web_account"
def password = new File("/run/secrets/proxy_password").text.trim()
final String noProxyHost = "127.0.0.1,localhost,mycompany.com"

final def pc = new hudson.ProxyConfiguration(name, port, username, password, noProxyHost)
instance.proxy = pc
instance.save()
pc.save()
println "Proxy settings updated!"

我需要定义一个管理员帐户：

$ more security.groovy

#!groovy

import jenkins.model.*
import hudson.security.*
import jenkins.security.s2m.AdminWhitelistRule

def instance = Jenkins.getInstance()

def user = new File("/run/secrets/jenkins-adm-name").text.trim()
def pass = new File("/run/secrets/jenkins-adm-pass").text.trim()

println "Creating user " + user + "..."

def hudsonRealm = new HudsonPrivateSecurityRealm(false)
hudsonRealm.createAccount(user, pass)
instance.setSecurityRealm(hudsonRealm)

def strategy = new FullControlOnceLoggedInAuthorizationStrategy()
instance.setAuthorizationStrategy(strategy)
instance.save()

Jenkins.instance.getInjector().getInstance(AdminWhitelistRule.class).setMasterKillSwitch(false)

println "User " + user + " was created"

最后，我不想在主人身上执行任何工作：

$ more master-executors.groovy

import hudson.model.*;
import jenkins.model.*;

println "--> disabling master executors"
Jenkins.instance.setNumExecutors(0)

使用最新的jenkins
