Windows Server 2019 容器化探索-Docker安装

Docker on Windows Server 2019

微软自Windows Server 2016开始支持Docker，今天我们将介绍在Windows Server 2019上安装并使用Docker容器。

Install Docker EE on windows server 2019

1. 启用服务器Hyper-V,Containers特性

Install-WindowsFeature -Name Hyper-V,Containers -IncludeAllSubFeature -IncludeManagementTools

1. Install Docker EE

Install-Module DockerMSFTProvider

Import-Module -Name DockerMSFTProvider -Force

Import-Packageprovider -Name DockerMSFTProvider -Force

通过Find-Package docker确认是否安装成功

PS C:\Users\Administrator> Find-Package docker

Name                           Version          Source           Summary
----                           -------          ------           -------

Docker                         18.09.5          DockerDefault    Contains Docker EE for use with Windows Server.

安装Docker

Install-Package -Name Docker -Source DockerDefault 

启用Docker Linux Container Support

目前基于Windows Container只能运行Windows应用程序。

# Set LCOW_SUPPORTED Variable to 1 for enabled
[Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine")

# Enable Experimental Features in Dockerd daemon.conf
$configfile = @"
{
    "experimental": true
}
"@
$configfile|Out-File -FilePath C:\ProgramData\docker\config\daemon.json -Encoding ascii -Force

在Docker使用 Linux Container时，仍然需要使用Linux kernal。

You should use the latest LCOW release here

Invoke-WebRequest -Uri "https://github.com/linuxkit/lcow/releases/download/v4.14.35-v0.3.9/release.zip" -UseBasicParsing -OutFile release.zip

Expand-Archive release.zip -DestinationPath "$Env:ProgramFiles\Linux Containers\."

Redis on Docker Linux Container

现在我们即可使用 Windows Container或者Linux Container，但是由于目前基于Windows Container只能运行Windows应用程序，所以我们需要使用--platform选择一种容器类型，参考如下

docker run --platform=linux --name redis-server -d -p 6379:6379 --restart=always redis
