我目前有一个可在本地运行并私有(private)托管在 hub.docker.com 上的 docker 镜像。
容器内有rails、puma、nginx。 Elastic beanstalk 能够从 docker hub 成功拉取镜像,但之后无法执行任何操作。
AWS 有 nginx,并且向我返回此错误。谁能指出我做错了什么?

错误的src文件
upstream docker {
server :80;
keepalive 256;
}
这是我拥有的文件。

最佳答案
问题在于 EC2 上的容器无法运行。 Amazon 使用此命令构建 IP 地址并设置环境变量。
EB_CONFIG_NGINX_UPSTREAM_IP=$(docker inspect `cat $EB_CONFIG_DOCKER_STAGING_APP_FILE` | jq -r .[0].NetworkSettings.IPAddress)
然后亚马逊使用此行来构建 IP 地址。
EB_CONFIG_NGINX_UPSTREAM_PORT=`cat $EB_CONFIG_DOCKER_STAGING_PORT_FILE`
我的端口 80 已暴露,但由于我的容器无法运行,所以我没有主机。这就是您收到此错误的原因。
上游“:80”中没有主机
