一台笔记本电脑，Windows操作系统，安装了VirtualBox，Vagrant，Github。
操作系统Oracle Linux 7，运行容器数据库，数据库企业版，RAC，版本为19.3.0，实例名为ORCLCDB，带一个可插拔数据库orclpdb1。两个RAC节点均运行于同一主机。
克隆项目以获得Linux Vagrant Box：
PS D:\DB> git clone https://github.com/oracle/vagrant-boxes.git
安装磁盘扩展插件：
vagrant plugin install vagrant-disksize
在Vagrantfile中将内存由默认的2048改为8192，然后修改根盘的大小为80G。如下:
...
config.vm.box = "ol7-latest"
config.disksize.size = "80GB"
config.vm.box_url = "https://yum.oracle.com/boxes/oraclelinux/latest/ol7-latest.box"
config.vm.define NAME
config.vm.box_check_update = false
# change memory size
config.vm.provider "virtualbox" do |v|
v.memory = 8192
v.name = NAME
end
...然后创建虚机（Oracle Linux 7）。耗时7分42秒，我的环境一般在7分钟左右。
PS E:\DB\vagrant-boxes\OracleLinux\7> vagrant up
启动VM后，磁盘是64G，但根分区仍是32G:
$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 3.8G 0 3.8G 0% /dev
tmpfs 3.8G 0 3.8G 0% /dev/shm
tmpfs 3.8G 8.5M 3.8G 1% /run
tmpfs 3.8G 0 3.8G 0% /sys/fs/cgroup
/dev/mapper/vg_main-lv_root 32G 1.7G 31G 6% /
/dev/sda1 497M 125M 373M 26% /boot
vagrant 1.9T 1.1T 753G 60% /vagrant
tmpfs 771M 0 771M 0% /run/user/1000
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 0 15.6G 0 disk
sda 8:0 0 80G 0 disk
├─sda2 8:2 0 36G 0 part

│ └─vg_main-lv_root 252:0 0 32G 0 lvm /
└─sda1 8:1 0 500M 0 part /boot
因此需要扩展分区，大致过程如下：
fdisk /dev/sda (n, p, <Enter>, <Enter>, w) -> 产生新分区/dev/sda3
partprobe
pvcreate /dev/sda
vgextend vg_main /dev/sda3
lvextend /dev/vg_main/lv_root /dev/sda3
xfs_growfs /扩容后的空间：
# df -h

devtmpfs 3.8G 0 3.8G 0% /dev
tmpfs 3.8G 0 3.8G 0% /dev/shm

tmpfs 3.8G 0 3.8G 0% /sys/fs/cgroup
/dev/mapper/vg_main-lv_root 76G 1.7G 74G 3% /

vagrant 1.9T 1.1T 753G 60% /vagrant
tmpfs 771M 0 771M 0% /run/user/1000
以下操作均登入Linux中运行。
安装Docker，耗时0m49.161s：
sudo yum install -y yum-utils
sudo yum-config-manager --enable ol7_addons
sudo yum install -y docker-engine
sudo systemctl start docker
sudo systemctl enable docker
sudo usermod -aG docker vagrant确认docker安装成功:
$ docker version

耗时0m31.599s：
sudo yum install -y git
git clone https://github.com/oracle/docker-images.gitdocker会从Host OS继承参数，因此需在文件/etc/sysctl.conf中设置以下参数：
fs.file-max = 6815744
net.core.rmem_max = 4194304
net.core.rmem_default = 262144
net.core.wmem_max = 1048576
net.core.wmem_default = 262144
net.core.rmem_default = 262144使其生效：
sudo sysctl -a
sudo sysctl -p
docker network create --driver=bridge --subnet=172.16.1.0/24 rac_pub1_nw
docker network create --driver=bridge --subnet=192.168.17.0/24 rac_priv1_nw
查看状态：
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
aac5636fe8fc bridge bridge local
051a1439f036 host host local
1a9007862a18 none null local
fe35e54e1aa0 rac_priv1_nw bridge local
0c6bdebeab78 rac_pub1_nw bridge local
RAC的某些进程需要运行在实时模式，因此需要在文件/etc/sysconfig/docker中添加以下：
OPTIONS=‘--selinux-enabled --cpu-rt-runtime=950000‘
使其生效：
sudo systemctl daemon-reload
sudo systemctl stop docker
sudo systemctl start docker
SELINUX 配置为 permissive模式（/etc/selinux/config），过程略。
然后重启实例使得SELINUX生效。
此时的空间状态：
$ df -h

vagrant 1.9T 1.1T 753G 60% /vagrant
tmpfs 771M 0 771M 0% /run/user/1000耗时真的看运气，有时7分钟，最近一次1分半：
cd docker-images/OracleDatabase/RAC/OracleRealApplicationClusters/dockerfiles/19.3.0
cp /vagrant/LINUX.X64_193000_db_home.zip .
cp /vagrant/LINUX.X64_193000_grid_home.zip .

vagrant 1.9T 1.1T 745G 61% /vagrant
tmpfs 771M 0 771M 0% /run/user/1000这一步最重要的任务就是拷贝介质和配置脚本，还有从网络下载OS更新。然后安装GI和数据库。
执行以下命令开始构建：
$ cd docker-images/OracleDatabase/RAC/OracleRealApplicationClusters/dockerfiles
$ ls

$ time ./buildDockerImage.sh -v 19.3.0如果空间不够，会报错：
