1.5 安裝 docker
參考：Get Docker | Docker Documentation 或者
echo " net.ipv4.ip_forward = 1 net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1" >> /etc/sysctl.conf sysctl -p curl https://releases.rancher.com/install-docker/19.03.sh | sh systemctl enable docker
設置國內源
vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://hccwwfjl.mirror.aliyuncs.com"]
}
systemctl restart docker其他源：http://hub-mirror.c.163.com，建議用這個 163 的
1.6 安裝 docker machine
參考：Testing Environment | GitLab
$ curl -L https://github.com/docker/machine/releases/download/v0.16.2/docker-machine-`uname -s`-`uname -m` >/usr/local/bin/docker-machine && \ chmod +x /usr/local/bin/docker-machine $ docker-machine version docker-machine version 0.16.2, build bd45ab13
2. 安裝極狐gitlab

export SSH_PORT=2222 export HTTP_PORT=8888 export VERSION=15.1.2 export ENV_NAME=gitlab-test-env export CONTAINER_NAME=gitlab-test-14.7.3
2.3 創建 docker host
docker-machine create \ --virtualbox-cpu-count -1 \ --virtualbox-memory 4096 \ --virtualbox-disk-size 30000 \ --driver virtualbox $ENV_NAME
會出現以下報錯
Creating CA: /root/.docker/machine/certs/ca.pem Creating client certificate: /root/.docker/machine/certs/cert.pem Running pre-create checks... Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
原因是未安裝 VirtualBox，解決方法如下
Linux_Downloads – Oracle VM VirtualBox
wget https://download.virtualbox.org/virtualbox/6.1.32/VirtualBox-6.1-6.1.32_149290_el7-1.x86_64.rpm yum install -y VirtualBox-6.1-6.1.32_149290_el7-1.x86_64.rpm
必須使用 yum 安裝 rpm 包，以便解決依賴
再次運行 docker-machine 創建命令，出現以下報錯：
Running pre-create checks... Error with pre-create check: "We support Virtualbox starting with version 5. Your VirtualBox install is \"WARNING: The vboxdrv kernel module is not loaded.

There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root. If your system is using EFI Secure Boot you may need to sign the
kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load
them. Please see your Linux system's documentation for more information.
根據提示執行
yum install -y gcc make perl # 會提示找不到 kernel-devel-5.4.180-1.el7.elrepo.x86_64 yum install -y kernel-devel kernel-devel-5.4.180-1.el7.elrepo.x86_64
原因是前面我們升級了內核到 5.4，內核太新了，重新使用默認 3.10 內核

成功編譯進內核
再次執行 docker-machine，還是報錯：
Running pre-create checks... Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
原因是 vm 未開啟硬件虛擬化，關閉虛擬機，開啟即可
圖片此處省略
- 勾選
虛擬化 Intel VT-X/EPT 或 AMD-V/RVI(V)
重啟后再次運行 docker-machine，結果因為網絡原因下載鏡像失敗
Running pre-create checks... (gitlab-test-env) No default Boot2Docker ISO found locally, downloading the latest release...

解決方法很簡單，先在合適網絡下下載 https://github.com/boot2docker/boot2docker/releases/download/v19.03.12/boot2docker.iso，然后把 boot2docker.iso 放到目錄 /root/.docker/machine/cache/ 下即可
再次運行 docker-machine

解決方法如下：
1. docker-machine ls 的所有計算機
2. 用 docker-machine rm -y <machineName> 刪除它們
3. 用 VBoxManage list hostonlyifs 查找所有 host-only 以太網適配器
4. 用 VBoxManage hostonlyif remove <networkName> 逐個刪除它們
5. 創建 /etc/vbox 文件夾
6. 寫入文件 echo "* 0.0.0.0/0 ::/0" > /etc/vbox/networks.conf
這種解決方法可能會導致啟動 docker 機器時 Waiting for an IP...會花費多一點時間
再次創建 host，正常運行了
