etcd2 falha ao iniciar no meu nó CoreOS

Question

Estou tentando iniciar o etcd2 no meu nó CoreOS.

Eu tenho isso no meu cloud-config:

coreos:
  etcd2:
    discovery: https://discovery.etcd.io/new?size=1
    advertise-client-urls: http://127.0.0.1:2379,http://127.0.0.1:4001
    initial-advertise-peer-urls: http://127.0.0.1:2380
    listen-client-urls: http://0.0.0.0:2379,http://0.0.0.0:4001
    listen-peer-urls: http://127.0.0.1:2380

Após a instalação, quando eu inicializo o sistema, recebo o erro (de acordo com os logs):

etcdmain: invalid character 'p' after top-level value

e o etcd2 falha ao iniciar.

O que isso significa? Eu segui os guias no link e link .

Answer 1

Seu URL de descoberta está incorreto - o URL https://discovery.etcd.io/new?size=1 é usado para obter um novo URL de descoberta que você pode usar em sua configuração. Faça isso uma vez manualmente, por ex. com ondulação:

curl --silent -H "Accept: text/plain" https://discovery.etcd.io/new?size=1

Isso retornará um URL como este:

https://discovery.etcd.io/a93e30ebf9375f2385fef54c83b2840d

É um URL como esse que deve ser seu URL de descoberta. Sempre use uma nova URL de descoberta sempre que você criar um novo cluster.

    

Answer 2

Se esse é todo o arquivo cloud-config.yml, então está errado.

A primeira linha do arquivo precisa ser:

#cloud-config

ou seja,

#cloud-config

coreos:
  etcd2:
    discovery: https://discovery.etcd.io/new?size=1
    advertise-client-urls: http://127.0.0.1:2379,http://127.0.0.1:4001
    initial-advertise-peer-urls: http://127.0.0.1:2380
    listen-client-urls: http://0.0.0.0:2379,http://0.0.0.0:4001
    listen-peer-urls: http://127.0.0.1:2380

Além disso, tenha cuidado ao copiar o cloud-config de um site. Eu tive alguns caracteres estranhos escondidos no arquivo de saída resultante que causou erros do analisador e resultando em falha!
