Faça o upload dos arquivos lxd.tar.xz e rootfs.squashfs, adicione a imagem ao repositório e crie um contêiner:
lxcimageimportlxd.tar.xzrootfs.squashfs--aliasalpine# Check the image is therelxcimagelist# Create the containerlxcinitalpineprivesc-csecurity.privileged=true# List containerslxclistlxcconfigdeviceaddpriveschost-rootdisksource=/path=/mnt/rootrecursive=true
Se encontrar este erro Erro: Nenhum pool de armazenamento encontrado. Por favor, crie um novo pool de armazenamento
Execute lxd init e repita o bloco anterior de comandos
Finalmente, você pode executar o contêiner e obter acesso root:
lxcstartprivesclxcexecprivesc/bin/sh[email protected]:~# cd /mnt/root #Here is where the filesystem is mounted
Método 2
Construa uma imagem Alpine e inicie-a usando a flag security.privileged=true, forçando o contêiner a interagir como root com o sistema de arquivos do host.
