OpenStack镜像的构建

概述

OpenStack镜像的构建有许多种方法，可以直接利用别人构建好的镜像，也可以手动构建，也可以使用镜像构建工具实现镜像构建的自动化，这里主要讲后面两种。

获取镜像

关于如何获取镜像，OpenStack官网上已经说的足够清楚了，这里就不赘述了，可以直接去官网查看。

手动构建镜像

这里以构建centos 7的镜像为例子，我的环境也是centos7。

yum -y install qemu-kvm libvirt virt-install bridge-utils
modprobe kvm
# make sure modules are loaded
lsmod | grep kvm
systemctl start libvirtd
systemctl enable libvirtd


virt-install \
--name centos7 \
--ram 1024 \
--disk path=/var/kvm/images/centos7.img,size=30 \
--vcpus 1 \
--os-type linux \
--os-variant centos7.0 \
--network bridge=br0 \
--graphics none \
--console pty,target_type=serial \
--location 'https://mirrors.huaweicloud.com/centos/7/os/x86_64/' \
--extra-args 'console=ttyS0,115200n8 serial'

dracut-initqueue[744]: Warning: dracut-initqueue timeout - starting timeout scripts

virt-install \

diskimage-builder（简称为DIB）是一个用于自动构建自定义的操作系统镜像的工具，以便在云和其他环境中使用。

构建docker容器

利用docker容器来搭建镜像的环境，这里选择centos镜像，同时将本地目录和容器内的文件目录做一个映射。

1	docker run -itd --privileged=true --name centos -v $PWD:/root centos:7 /sbin/init

安装

依赖环境

进入容器内安装DIB的依赖环境。

docker exec -it centos bash
yum update
yum install -y epel-release 
yum install -y python3 git sudo        # DIB需要Python3支持
pip3 install -U pip setuptools wheel

安装qemu-img和kpartx。

1 2	apt-get install qemu-utils kpartx squashfs-tools e4fsprogs # ubuntu yum install -y qemu-img kpartx squashfs-tools e4fsprogs # centos

DIB

从github将DIB下载下来。

1	git clone https://github.com/openstack/diskimage-builder.git

切换到最近的tag上，我这里是3.7.0。

1 2	cd diskimge-builder git checkout -b v3.7.0 3.7.0

设置虚环境

1 2	pip install virtualenv mkdir venv && cd venv && virtualenv -p /usr/bin/python3 diskimage-builder

安装diskimage-builder。

1	cd /root/diskimage-builder && /root/venv/diskimage-builder/bin/pip install -e .

测试


[root@centos-linux ~]# disk-image-create -h
Usage: disk-image-create [OPTION]... [ELEMENT]...

Options:
    -a i386|amd64|armhf|arm64 -- set the architecture of the image(default amd64)
    -o imagename -- set the imagename of the output image file(default image)
    -t qcow2,tar,tgz,squashfs,vhd,docker,aci,raw -- set the image types of the output image files (default qcow2)
       File types should be comma separated. VHD outputting requires the vhd-util
       executable be in your PATH. ACI outputting requires the ACI_MANIFEST
       environment variable be a path to a manifest file.
    -x -- turn on tracing (use -x -x for very detailed tracing).
    -u -- uncompressed; do not compress the image - larger but faster
    -c -- clear environment before starting work
    --logfile -- save run output to given logfile (implies DIB_QUIET=1)
    --checksum -- generate MD5 and SHA256 checksum files for the created image
    --image-size size -- image size in GB for the created image
    --image-extra-size size -- extra image size in GB for the created image
    --image-cache directory -- location for cached images(default ~/.cache/image-create)
    --max-online-resize size -- max number of filesystem blocks to support when resizing.
       Useful if you want a really large root partition when the image is deployed.
       Using a very large value may run into a known bug in resize2fs.
       Setting the value to 274877906944 will get you a 1PB root file system.
       Making this value unnecessarily large will consume extra disk space
       on the root partition with extra file system inodes.
    --min-tmpfs size -- minimum size in GB needed in tmpfs to build the image
    --mkfs-journal-size -- filesystem journal size in MB to pass to mkfs.
    --mkfs-options -- option flags to be passed directly to mkfs.
       Options should be passed as a single string value.
    --no-tmpfs -- do not use tmpfs to speed image build
    --offline -- do not update cached resources
    --qemu-img-options -- option flags to be passed directly to qemu-img.
       Options need to be comma separated, and follow the key=value pattern.
    --root-label label -- label for the root filesystem.  Defaults to 'cloudimg-rootfs'.
    --ramdisk-element -- specify the main element to be used for building ramdisks.
       Defaults to 'ramdisk'.  Should be set to 'dracut-ramdisk' for platforms such
       as RHEL and CentOS that do not package busybox.
    --install-type -- specify the default installation type. Defaults to 'source'. Set to 'package' to use package based installations by default.
    --docker-target -- specify the repo and tag to use if the output type is docker. Defaults to the value of output imagename
    -n skip the default inclusion of the 'base' element
    -p package[,p2...] [-p p3] -- extra packages to install in the image.  Runs once, after 'install.d' phase.  Can be specified multiple times
    -h|--help -- display this help and exit
    --version -- display version and exit

Environment Variables:
  (this is not a complete list)

  * ELEMENTS_PATH: specify external locations for the elements.  As for $PATH
  * DIB_NO_TIMESTAMP: no timestamp prefix on output.  Useful if capturing output
  * DIB_QUIET: 1=do not output log output to stdout; 0=always ouptut to stdout.  See --logfile

NOTE: At least one distribution root element must be specified.

NOTE: If using the VHD output format you need to have a patched version of vhd-util installed for the image
      to be bootable. The patch is available here: https://github.com/emonty/vhd-util/blob/master/debian/patches/citrix
      and a PPA with the patched tool is available here: https://launchpad.net/~openstack-ci-core/+archive/ubuntu/vhd-util

Examples:
    disk-image-create -a amd64 -o ubuntu-amd64 vm ubuntu
    export ELEMENTS_PATH=~/source/tripleo-image-elements/elements
    disk-image-create -a amd64 -o fedora-amd64-heat-cfntools vm fedora heat-cfntools

创建ubuntu镜像。

1	/root/venv/diskimage-builder/bin/disk-image-create -a amd64 -o ubuntu-amd64 vm ubuntu

Elements

DIB中的elements

DIB中有大量的元件。DIB的元件在diskimage-builder项目中的/diskimage_builder/elements的目录下。

自定义elements

可以自行编写elements来满足构建镜像的要求。

#!/bin/bash

set -e
set -o xtrace

source $_LIB/die

[ -n "$TMP_HOOKS_PATH" ] || die "Temp hook path not set"
[ -n "$HOST_USERNAME" ] || die "HOST_USERNAME not set"

cp -r ${PATH_TROVE} ${TMP_HOOKS_PATH}/
REQUIREMENTS_FILE=${TROVESTACK_SCRIPTS}/files/requirements/centos-requirements.txt
sudo -Hiu ${HOST_USERNAME} dd if=${REQUIREMENTS_FILE} of=${TMP_HOOKS_PATH}/requirements.txt

Trove中的elements

除了DIB提供的元件，Trove也提供自己所支持的数据库的元件。可以在trove项目下的integration/scripts/files/elements中找到trove的相关元件。

Trove镜像构建

下载Trove

从github上将trove项目下载到本地，位置和DIB存放的一致，都在/root下。

1	git clone https://git.openstack.org/openstack/trove.git

说明

HOST_USERNAME

HOST_USERNAME is the name of the user on the Trove host machine. It is used to identify the location of the authorized_keys, id_rsa, and id_rsa_pub files that are to be in guest image creation.

HOST_SCP_USERNAME

HOST_SCP_USERNAME is the name of the user on the Trove host machine used to connect from the guest while copying the guest agent code during the upstart process.

GUEST_USERNAME

GUEST_USERNAME is the name of the user on the Trove guest who will run the guest agent and perform a number of other jobs. This user is created during the image build process if it does not exist.

CONTROLLER_IP

CONTROLLER_IP

TROVESTACK_SCRIPTS

TROVESTACK_SCRIPTS is the pointer to files in the trove project.

SERVICE_TYPE

SERVICE_TYPE

PATH_TROVE

PATH_TROVE is the path to the Trove source code and this is used in the rsync of code to the guest.

ESCAPED_PATH_TROVE

ESCAPED_PATH_TROVE is the escaped version of PATH_TROVE and is used for much the same purpose as PATH_TROVE.

SSH_DIR

SSH_DIR is a path to the .ssh directory for the user on the host and is used in the image creation process to obtain the authorized_keys, id_rsa and id_rsa_pub files.

GUEST_LOGDIR

GUEST_LOGDIR is the location on the guest where the Trove log file is to be stored.

ESCAPED_GUEST_LOGDIR

ESCAPED_GUEST_LOGDIR is the escaped version of GUEST_LOGDIR.

DIB_CLOUD_INIT_DATASOURCES

DIB_CLOUD_INIT_DATASOURCES . The DIB element cloud-init-datasources uses this value to determine the data sources that must be queried during first boot to obtain instance metadata.

DATASTORE_PKG_LOCATION

DATASTORE_PKG_LOCATION is not used in the creation of the Mysql instance but is used by some databases (currently DB2 and Vertica) to identify the location of a downloaded package containing the database. Other databases merely obtain this using apt-get or appropriate package management command. This variable is used for databases that do not allow this, and for example, require the user to click on a license agreement in order to obtain the database software.

RELEASE

RELEASE是我自己后加入的，不加的话会有报错，后面会提到。

构建镜像

构建镜像使用的命令是disk-image-create。

(diskimage-builder) wkt@controller-1:~$ disk-image-create --help
Usage: disk-image-create [OPTION]... [ELEMENT]...

Options:
    -a i386|amd64|armhf|arm64 -- set the architecture of the image(default amd64)
    -o imagename -- set the imagename of the output image file(default image)
    -t qcow2,tar,tgz,squashfs,vhd,docker,aci,raw -- set the image types of the output image files (default qcow2)
       File types should be comma separated. VHD outputting requires the vhd-util
       executable be in your PATH. ACI outputting requires the ACI_MANIFEST
       environment variable be a path to a manifest file.
    -x -- turn on tracing (use -x -x for very detailed tracing).
    -u -- uncompressed; do not compress the image - larger but faster
    -c -- clear environment before starting work
    --logfile -- save run output to given logfile

    -h|--help -- display this help and exit
    --version -- display version and exit

Environment Variables:
  (this is not a complete list)

  * ELEMENTS_PATH: specify external locations for the elements.  As for $PATH
  * DIB_NO_TIMESTAMP: no timestamp prefix on output.  Useful if capturing output
  * DIB_QUIET: do not output log output to stdout.  See --logfile

NOTE: At least one distribution root element must be specified.

      to be bootable. The patch is available here: https://github.com/emonty/vhd-util/blob/master/debian/patches/citrix
      and a PPA with the patched tool is available here: https://launchpad.net/~openstack-ci-core/+archive/ubuntu/vhd-util

Examples:
    disk-image-create -a amd64 -o ubuntu-amd64 vm ubuntu
    export ELEMENTS_PATH=~/source/tripleo-image-elements/elements
    disk-image-create -a amd64 -o fedora-amd64-heat-cfntools vm fedora heat-cfntools

一旦设置好前面的变量可以用下面的命令创建Mysql数据库的Trove Guest镜像。

1	disk-image-create -a amd64 -o ubuntu-xenial-mysql -x --qemu-img-options compat=1.1 ubuntu vm cloud-init-datasources ubuntu-guest ubuntu-xenial-guest ubuntu-mysql ubuntu-xenial-mysql

这会默认生成qcow2格式的镜像，并储存在当前路径下。

出错的话，可以查看出现问题。

注册镜像

构建了镜像就需要在Glance和Trove中注册。首先，在Glance注册一个Guest镜像。获得镜像的id

openstack image create ubuntu-xenial-mysql --file ubuntu-xenial-mysql.qcow2 --disk-format qcow2 --container-format bare --public --property image_type=distribution --property image_label=Test --property expected_size=10 --property hw_qemu_guest_agent='yes’

进入到trove-api的Docker中。

1 2	root@controller-1:~# docker ps \| grep trove root@controller-1:~# docker exec -it trove_api bash

docker-ps

注册新的数据库类型

1	trove-manage --config-file=/etc/trove/trove.conf datastore_update mysql ''

已经存在数据库类型可跳过此步。

更新mysql数据库的版本信息

1	trove-manage --config-file=/etc/trove/trove.conf datastore_version_update mysql <版本> mysql <镜像id> '' 1

第一个参数
指的是数据库的类型
第二个参数
指的是数据库的版本号
第三个参数
指的是数据库管理类的名字,可以根据类名关联到Trove guest agent内的特定数据库类型。对Mysql而言，其对应的管理类就是trove.guestagent.datastore.mysql.manager.Manager。Trove支持的每一个数据库都有相应的Manage类，其类名可以在各种Trove配置文件中通过参数进行配置。
第四个参数
指的是镜像的id。此id是之前的openstack image create命令输出中提供的。
第五个参数
是传递到guest agent的prepare()信息中的安装包名称列表，通常用于guest agent安装最新的软件包或更新软件包到最新版本。这里为空。
第六个参数
将数据库版本标记为活跃。

可以通过执行trove-manage datastore_version_update -h命令获取所有的帮助信息。

出现问题

解决问题
将trove/integration/scripts/files/elements/ubuntu-mysql/pre-install.d/10-percona-apt-key中的

get_key_robust 1C4CBDCDCD2EFD2A
get_key_robust 9334A25F8507EFA5

# Add Percona repo
# Creates the percona sources list
cat <<EOL > /etc/apt/sources.list.d/percona.list
deb http://repo.percona.com/apt $RELEASE main
deb-src http://repo.percona.com/apt $RELEASE main
EOL

改为

get_key_robust 1C4CBDCDCD2EFD2A
get_key_robust 9334A25F8507EFA5

apt-get install -y apt-transport-https

# Add Percona repo

cat <<EOL > /etc/apt/sources.list.d/percona.list
deb https://repo.percona.com/apt $RELEASE main
