3.2 volúmenes
mkdir -p /var/jenkins_mount
chmod 777 /var/jenkins_mount
3.3 Crear e iniciar el contenedor Jenkins
- -d ejecuta la imagen en segundo plano
- -p 10240:8080 asigna el puerto 8080 del espejo al puerto 10240 del servidor.
- -p 10241:50000 asigna el puerto 50000 del espejo al puerto 10241 del servidor
- -v /var/jenkins_mount:/var/jenkins_mount El directorio /var/jenkins_home es el directorio de trabajo del contenedor jenkins. Montamos un directorio en el disco duro en esta ubicación para facilitar el uso posterior del directorio de trabajo original después de actualizar el imagen. Lo que configuramos aquí es el directorio /var/jenkins_mount que creamos arriba
- -v /etc/localtime:/etc/localtime le dice al contenedor que use la misma configuración de hora que el servidor.
- –name myjenkins Dale un alias al contenedor

3.5 Modificar dirección de origen
Si la extracción de contenido es lenta, puede intentar cambiar la dirección de aceleración de la imagen.
Dado que los volúmenes están configurados, puede modificar la configuración sin iniciar sesión en el contenedor. Vaya a /var/jenkins_mount
y modifique hudson.model.UpdateCenter.xml para
<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url>
</site>
</sites>
3.6 Acceder a la página principal
localhost: 10240
Ingrese la dirección en el contenedor o la dirección de montaje para obtener la contraseña e ingrésela. Después de instalar un montón de complementos,
no configuré un usuario administrador aquí y usé la cuenta de administrador.
