De acordo com as informações de log fornecidas, o motivo pelo qual o serviço Docker falha ao iniciar é que o daemon Docker não pode ser configurado para usar o arquivo de configuração especificado. /etc/docker/daemon.json
Como o arquivo de configuração não foi tocado, é basicamente impossível para erros de sintaxe ou similares
Solução
Primeiro faça backup do arquivo de configuração original [opcional, recomendado]
mv /etc/docker/daemon.json /etc/docker/daemon.json.bak
Em seguida, crie um arquivo de configuração vazio
touch /etc/docker/daemon.json
Em seguida, reinicie a janela de encaixe, inicie e reinicie.Se não houver
acidente, será resolvido com sucesso! !
