Empresa Microsoft anunciou<\/a><\/noindex> sobre a disponibiliza\u00e7\u00e3o do suporte ao subsistema WSL2<\/a><\/noindex> (Windows Subsystem for Linux) nas vers\u00f5es do Windows 10 \u2014 1903 e 1909, lan\u00e7adas em maio e novembro do ano passado. Originalmente, o subsistema WSL2, que permite a execu\u00e7\u00e3o de arquivos execut\u00e1veis do Linux no Windows, foi introduzido na vers\u00e3o do Windows 10 2004. Agora, a Microsoft transferiu esse subsistema para as atualiza\u00e7\u00f5es anteriores do Windows 10, que continuam relevantes e s\u00e3o utilizadas em muitas empresas. A portabilidade do WSL2 para essas vers\u00f5es permitir\u00e1 uma execu\u00e7\u00e3o eficiente do ambiente Linux sem a necessidade de atualizar para o Windows 10 2004 (suporte para as vers\u00f5es 1903 e 1909). se estender\u00e1<\/a><\/noindex> at\u00e9 dezembro de 2020 e maio de 2022).

\"A<\/a><\/noindex><\/center><\/p>\n

Lembramos que a edi\u00e7\u00e3o do WSL2 caracteriza-se<\/a><\/noindex> substituiu o n\u00facleo do Linux completo em vez do emulador anteriormente utilizado, que fazia a tradu\u00e7\u00e3o de chamadas de sistema do Linux para chamadas de sistema do Windows. O n\u00facleo do Linux no WSL2 n\u00e3o est\u00e1 inclu\u00eddo na imagem de instala\u00e7\u00e3o do Windows, mas \u00e9 carregado dinamicamente e mantido atualizado pela equipe do Windows, semelhante \u00e0 forma como drivers gr\u00e1ficos s\u00e3o instalados e atualizados. O mecanismo padr\u00e3o do Windows Update \u00e9 utilizado para a instala\u00e7\u00e3o e atualiza\u00e7\u00e3o do n\u00facleo.<\/p>\n

O n\u00facleo proposto para o WSL2 baseia-se na vers\u00e3o 4.19 do n\u00facleo Linux, que opera em um ambiente Windows com a ajuda de uma m\u00e1quina virtual j\u00e1 utilizada no Azure. Os patches espec\u00edficos do WSL2 aplicados no n\u00facleo incluem otimiza\u00e7\u00f5es para reduzir o tempo de inicializa\u00e7\u00e3o do n\u00facleo, diminuir o consumo de mem\u00f3ria, retornar \u00e0 Windows a mem\u00f3ria liberada pelos processos do Linux e deixar no n\u00facleo um conjunto m\u00ednimo necess\u00e1rio de drivers e subsistemas.<\/a><\/noindex> O ambiente WSL2 \u00e9 executado em uma imagem de disco separada (VHD) com o sistema de arquivos ext4 e um adaptador de rede virtual. Assim como no WSL1, os componentes do espa\u00e7o do usu\u00e1rio <\/p>\n

s\u00e3o instalados separadamente e baseiam-se em vers\u00f5es de diferentes distribui\u00e7\u00f5es. Por exemplo, para instala\u00e7\u00e3o no WSL no diret\u00f3rio Microsoft Store,<\/a><\/noindex> Alpine s\u00e3o oferecidos<\/a><\/noindex> compila\u00e7\u00f5es Ubuntu<\/a><\/noindex>, Debian GNU\/Linux, Kali Linux<\/a><\/noindex>, Fedora<\/a><\/noindex>,
\nA Microsoft anunciou a expans\u00e3o da funcionalidade do subsistema WSL2.<\/a><\/noindex>, SUSE<\/a><\/noindex> e Arch Linux<\/a><\/noindex>. <\/p>\n

A Canonical j\u00e1 anunciou<\/a><\/noindex> anunciou a prontid\u00e3o das compila\u00e7\u00f5es de instala\u00e7\u00e3o do Ubuntu 20.04 LTS, testadas em ambientes
\n WSL2 baseados no Windows 10 1903 e 1909. Para ativar o WSL2 no Windows 10 1909, \u00e9 necess\u00e1rio instalar a atualiza\u00e7\u00e3o kb4571748<\/a><\/noindex> e executar no PowerShell com privil\u00e9gios de administrador o comando:<\/p>\n

Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -NoRestart<\/p>\n

Em seguida, deve-se reiniciar o computador e ativar o WSL2 como padr\u00e3o:<\/p>\n

wsl.exe \u2014set-default-version 2<\/p>\n

Depois disso, \u00e9 poss\u00edvel instalar o ambiente Linux desejado a partir do cat\u00e1logo
\nMicrosoft Store ou converter ambientes j\u00e1 existentes no formato WSL 1 usando o comando \u00abwsl.exe \u2014set-version Ubuntu 2\u00bb.<\/p>\n

Al\u00e9m disso, pode-se mencionar a adapta\u00e7\u00e3o<\/a><\/noindex> ambiente Docker Desktop<\/a><\/noindex> para uso<\/a><\/noindex> WSL2 em vez do backend baseado no HyperV.
\nO uso do WSL2 permitir\u00e1 executar o Docker Desktop n\u00e3o apenas para usu\u00e1rios do Windows Pro e Windows Enterprise, mas tamb\u00e9m para usu\u00e1rios do Windows Home.<\/p>\n
