Estou tentando definir o Couchbase e o sync_gateway em contêineres docker, mas recebo alguns erros de autenticação estranhos quando o sync_gateway tenta conectar o banco de dados.
O Couchbase está funcionando bem em seu contêiner e, quando eu configuro o sync_gateway para usar um usuário GUEST
, ele pode se conectar ao couchbase. O problema é que eu realmente quero usar o nome de usuário / senha que eu criei, então eu configurei o container couchbase.
Eu sei que o couchbase está funcionando porque eu posso acessá-lo pela interface web em localhost:8091
e fazer o login com o nome de usuário / senha que eu criei. Mas o sync_gateway levanta os erros que eu postei abaixo ao tentar acessar com o nome de usuário / senha do arquivo de configuração.
Dockerfile
FROM couchbase/server

Este é o entrypoint.sh
#!/bin/bash

}
server_configured() {
server_list=$(cb_cli server-list)
return $([[ $? == 0 ]] && [[ $(echo ${server_list} | wc -l) != 0 ]])
}
setup_couchbase_server() {
cb_cli cluster-init --cluster-ramsize=${RAM_SIZE} --cluster-username=admin --cluster-password=admin123
cb_cli bucket-create --bucket-ramsize=${RAM_SIZE} --bucket=${BUCKET_NAME}

done

}
}

E, finalmente, este é o erro que recebo quando executo o docker-compose up :
