Samuel Karp, engenheiro da Amazon, que trabalha no desenvolvimento da distribui\u00e7\u00e3o Linux Bottlerocket e de tecnologias de isolamento de containers para a AWS, est\u00e1 criando um novo runtime runj baseado em jail do FreeBSD para garantir a execu\u00e7\u00e3o isolada de containers alinhados \u00e0s especifica\u00e7\u00f5es da OCI (Open Container Initiative). O projeto \u00e9 posicionado como experimental, sendo desenvolvido em seu tempo livre e ainda estando na fase de prot\u00f3tipo. O c\u00f3digo \u00e9 escrito em Go e distribu\u00eddo sob a licen\u00e7a BSD. <\/p>\n

Ap\u00f3s o desenvolvimento atingir o n\u00edvel adequado, o projeto poder\u00e1 evoluir para permitir o uso do runj como substituto do runtime padr\u00e3o em sistemas Docker e Kubernetes, utilizando o FreeBSD em vez do Linux para executar containers. No runtime da OCI, atualmente, est\u00e3o implementados comandos para cria\u00e7\u00e3o, exclus\u00e3o, execu\u00e7\u00e3o, t\u00e9rmino for\u00e7ado e avalia\u00e7\u00e3o do estado dos containers. O conte\u00fado do container \u00e9 criado com base em um ambiente padr\u00e3o ou reduzido do FreeBSD. <\/p>\n

Como a especifica\u00e7\u00e3o da OCI ainda n\u00e3o suporta o FreeBSD, uma s\u00e9rie de par\u00e2metros adicionais relacionados \u00e0 configura\u00e7\u00e3o do jail e do FreeBSD foi desenvolvida no \u00e2mbito do projeto, com a inten\u00e7\u00e3o de incorpor\u00e1-los na especifica\u00e7\u00e3o principal da OCI. Para gerenciar o jail, s\u00e3o usadas as utilit\u00e1rios jail, jls, jexec, kill e ps do FreeBSD, sem acesso direto a chamadas de sistema. Entre os planos futuros, destaca-se a adi\u00e7\u00e3o de suporte para gerenciamento de limita\u00e7\u00e3o de recursos atrav\u00e9s da interface RCTL do n\u00facleo. <\/p>\n

Al\u00e9m do pr\u00f3prio runtime, o reposit\u00f3rio do projeto tamb\u00e9m est\u00e1 desenvolvendo uma camada experimental para uso junto com o runtime containerd (usado no Docker), modificado para suporte ao FreeBSD. Para converter o rootfs do FreeBSD em uma imagem de container compat\u00edvel com a OCI, uma utilit\u00e1rio especial \u00e9 proposto. Posteriormente, a imagem criada pode ser importada para o containerd.
