Desenvolvedores do projeto Fedora foi anunciado<\/a><\/noindex> sobre o in\u00edcio testes<\/a><\/noindex> da primeira vers\u00e3o preliminar da nova edi\u00e7\u00e3o da distribui\u00e7\u00e3o Fedora CoreOS<\/a><\/noindex>, que veio substituir os produtos Fedora Atomic Host e CoreOS Container Linux como uma solu\u00e7\u00e3o \u00fanica para executar ambientes baseados em cont\u00eaineres isolados.<\/p>\n

Do CoreOS Container Linux, que passou<\/a><\/noindex> caiu nas m\u00e3os da Red Hat ap\u00f3s a aquisi\u00e7\u00e3o da empresa CoreOS, foram transferidas para o Fedora CoreOS as ferramentas de implanta\u00e7\u00e3o (sistema de configura\u00e7\u00e3o na fase de inicializa\u00e7\u00e3o Ignition), o mecanismo de atualiza\u00e7\u00f5es at\u00f4micas e a filosofia geral do produto. Do Atomic Host, foram transferidas a tecnologia de gerenciamento de pacotes, o suporte \u00e0s especifica\u00e7\u00f5es OCI (Open Container Initiative) e mecanismos adicionais de isolamento de cont\u00eaineres baseados em SELinux. A infraestrutura do Fedora CoreOS \u00e9 formada com base nos reposit\u00f3rios do Fedora usando rpm-ostree. Os runtimes de cont\u00eaineres suportados no Fedora CoreOS incluem Moby (Docker) e podman. Para a orquestra\u00e7\u00e3o de cont\u00eaineres sobre o Fedora CoreOS, est\u00e1 prevista a integra\u00e7\u00e3o com o Kubernetes. <\/p>\n

O projeto visa fornecer um ambiente m\u00ednimo, atualizado automaticamente sem a participa\u00e7\u00e3o do administrador e padronizado para implanta\u00e7\u00e3o em massa de sistemas de servidores destinados exclusivamente \u00e0 execu\u00e7\u00e3o de cont\u00eaineres. O Fedora CoreOS cont\u00e9m apenas o conjunto m\u00ednimo de componentes necess\u00e1rio para a execu\u00e7\u00e3o de cont\u00eaineres isolados \u2014 o n\u00facleo Linux, o gerenciador de sistema systemd e um conjunto de servi\u00e7os auxiliares para conex\u00e3o por SSH, gerenciamento de configura\u00e7\u00e3o e instala\u00e7\u00e3o de atualiza\u00e7\u00f5es. <\/p>\n

A parti\u00e7\u00e3o do sistema \u00e9 montada em modo somente leitura e n\u00e3o \u00e9 alterada durante a opera\u00e7\u00e3o. Configura\u00e7\u00e3o<\/a><\/noindex> \u00e9 transmitido na fase de inicializa\u00e7\u00e3o atrav\u00e9s das ferramentas Ignition (alternativa ao Cloud-Init).
\nDepois que o sistema \u00e9 iniciado, a modifica\u00e7\u00e3o da configura\u00e7\u00e3o e do conte\u00fado do diret\u00f3rio \/etc \u00e9 imposs\u00edvel, \u00e9 apenas permitido alterar o perfil de configura\u00e7\u00e3o e us\u00e1-lo para substituir o ambiente. De maneira geral, o trabalho com o sistema lembra o trabalho com imagens de cont\u00eaineres, que n\u00e3o s\u00e3o atualizadas no local, mas reconstru\u00eddas do zero e reiniciadas.<\/p>\n

A imagem do sistema n\u00e3o \u00e9 divis\u00edvel e \u00e9 criada usando a tecnologia OSTree (pacotes separados n\u00e3o podem ser instalados nesse ambiente, apenas \u00e9 poss\u00edvel reconstruir toda a imagem do sistema, expandindo-a com novos pacotes atrav\u00e9s da ferramenta rpm-ostree). O sistema de atualiza\u00e7\u00f5es \u00e9 baseado no uso de duas parti\u00e7\u00f5es do sistema, uma das quais est\u00e1 ativa, enquanto a outra \u00e9 usada para copiar a atualiza\u00e7\u00e3o; ap\u00f3s a instala\u00e7\u00e3o da atualiza\u00e7\u00e3o, as parti\u00e7\u00f5es trocam de fun\u00e7\u00e3o. <\/p>\n

Tr\u00eas ramifica\u00e7\u00f5es independentes do Fedora CoreOS s\u00e3o oferecidas:
\n testing com snapshots baseados na vers\u00e3o atual do Fedora com atualiza\u00e7\u00f5es; stable \u2014 ramo estabilizado, gerado ap\u00f3s duas semanas de testes do ramo testing; next \u2014 snapshot do pr\u00f3ximo lan\u00e7amento em desenvolvimento. Para todos os tr\u00eas ramos, s\u00e3o geradas atualiza\u00e7\u00f5es para corre\u00e7\u00e3o de vulnerabilidades e erros graves. Neste est\u00e1gio atual de desenvolvimento, apenas o ramo testing est\u00e1 sendo formado dentro do pr\u00e9-lan\u00e7amento. O primeiro lan\u00e7amento est\u00e1vel est\u00e1 previsto para ser lan\u00e7ado em 6 meses. O suporte para a distribui\u00e7\u00e3o CoreOS Container Linux ser\u00e1 encerrado 6 meses ap\u00f3s a estabiliza\u00e7\u00e3o do Fedora CoreOS, enquanto o encerramento do suporte ao Fedora Atomic Host est\u00e1 previsto para o final de novembro.<\/p>\n

Ap\u00f3s a estabiliza\u00e7\u00e3o do projeto, o envio de telemetria ser\u00e1 ativado por padr\u00e3o (na vers\u00e3o preliminar a telemetria ainda n\u00e3o est\u00e1 ativa), utilizando o servi\u00e7o fedora-coreos-pinger, que periodicamente coleta e envia informa\u00e7\u00f5es n\u00e3o identificadoras sobre o sistema para os servidores do projeto Fedora, como o n\u00famero da vers\u00e3o do SO e a plataforma de nuvem do tipo de instala\u00e7\u00e3o. Nenhuma informa\u00e7\u00e3o que possa levar \u00e0 identifica\u00e7\u00e3o est\u00e1 inclu\u00edda nos dados transmitidos. Apenas dados agregados s\u00e3o usados para analisar as estat\u00edsticas e avaliar geralmente o uso do Fedora CoreOS. Se desejar, o usu\u00e1rio pode desativar o envio de telemetria ou expandir as informa\u00e7\u00f5es transmitidas por padr\u00e3o.<\/p>\n
