cobbler 3.3.4 配置ubuntu 22.04 自动安装

1.下载Ubuntu 22.04 iso 镜像

# https://releases.ubuntu.com/jammy/ubuntu-22.04.3-live-server-amd64.iso

mount -o loop ubuntu-22.04.3-live-server-amd64.iso /mnt
cp -r /mnt/* /iso   # /iso 目录已经映射到cobbler容器中
cp ubuntu-22.04.3-live-server-amd64.iso /iso

2.将ubuntu导入cobbler

• 将 iso 导入容器中

# 进入docker容器
cp /iso/ubuntu-22.04.3-live-server-amd64.iso /var/www/cobbler/pub/

• 生成 自动装机的 user-data 数据

# 生成用户密码
mkpasswd -m sha-512

　　

# 生成 user-data 文件，注意 storage部分，包含 /data，如果不需要，可以适当修改，注意必须有 #cloud-config
cat /var/lib/cobbler/templates/user-data
#cloud-config

• cobbler 操作

#检查是否有 ubuntu 22.04 的 signature，如果没有就执行update
cobbler signature report|grep jammy
cobbler signature update

# 导入镜像
cobbler import --arch=x86_64  --path=/iso/ubuntu-22.04.3 --name=ubu22

# 检查 distro 列表
cobbler distro list
# 会输出
ubu22-casper-x86_64

# 生成 cobbler loaders，目录 /var/lib/cobbler/loaders
cobbler mkloaders

# 导入 user-data 数据，cobbler 会查找 /var/lib/cobbler/templates/user-data
cobbler profile  edit --name=ubu22-casper-x86_64 --autoinstall=user-data

# 将 user-data 拷贝一份到 /var/www/cobbler/pub/目录，最后安装时根据 该目录下的文件来安装的
ln -s /var/lib/cobbler/templates/user-data /var/www/cobbler/pub/user-data
# 创建 meta-data 空文件
touch /var/www/cobbler/pub/meta-data 

# 执行 cobbler profile
cobbler profile edit --kernel-options="url=http://172.19.4.34/cblr/pub/ubuntu-22.04.3-live-server-amd64.iso \
ip=dhcp autoinstall \
