Elastic Beanstalk Worker 的 SQS 守护进程在 1 分钟后获得 504 网关超时 [英] Elastic Beanstalk Worker's SQS daemon getting 504 gateway timeout after 1 minute
问题描述
我有一个 Elastic Beanstalk 工作器,一次只能运行一项任务,并且需要一些时间(从几分钟到希望不到 30 分钟),所以我将我的任务排队SQS.
I have an Elastic Beanstalk worker that can only run one task at a time and it takes some time to do so (from a few minutes to, hopefully, less than 30 minutes), so I'm queuing my tasks on a SQS.
在我的工作器配置中,我有:
On my worker configuration, I have:
HTTP connections: 1
Visibility timeout: 3600
Error visibility timeout: 300
(On "Advanced")
Inactivity timeout: 1800
问题是似乎有 1 分钟超时(在 nginx 上?)覆盖了不活动超时",返回 504(网关超时).
The problem is that there seems to be a 1 minute timeout (on nginx?) that overrides the "Inactivity timeout", returning a 504 (Gateway timeout).
这是我可以在 aws-sqsd.log 文件中找到的内容:
This is what I can find on the aws-sqsd.log file:

这里有些事情是有意义的,比如每条消息从 504/500 的时间到任务再次重新发送给工作人员的 5 分钟延迟(这与错误可见性"的 300 秒配置相匹配超时").
Some things make sense here, like the 5 minute delay that each message takes from the time of the 504/500 until the task is re-sent to the worker once again (which matches the 300 seconds configuration for the "Error visibility timeout").
这 500 个代码符合我当前的逻辑:如果仍有一些东西在运行,worker 会通过抛出 500 来拒绝任务.
Those 500 codes match my current logic: the worker rejects the task by throwing a 500 back if there's still something running.
我已经看到很多关于设置负载均衡器连接超时设置的答案,但是,由于这是一个从 SQS 队列中提取消息的工作器,因此没有负载均衡器.
I have seen a lot of answers talking about setting the Load Balancer connection timeout setting, but, since this is a worker pulling messages from a SQS queue, there is no Load Balancer.
知道我应该怎么做才能覆盖 1 分钟超时设置吗?
Any idea on what I should do to override that 1 minute timeout setting?
推荐答案
由于我有时间调查这个问题好一点,解决方案是添加一个配置代理超时设置的 ebextension:
Since I had the time to investigate this a little better, the solution is to add an ebextension that configures the proxy timeout settings:
files:
"/etc/nginx/sites-available/elasticbeanstalk-nginx-docker-proxy-timeout.conf":
mode: "000644"
owner: root
group: root
content: |
proxy_connect_timeout 3600;
proxy_send_timeout 3600;
proxy_read_timeout 3600;
send_timeout 3600;
commands:
"00nginx-create-proxy-timeout":
command: "if [[ ! -h /etc/nginx/sites-enabled/elasticbeanstalk-nginx-docker-proxy-timeout.conf ]] ; then ln -s /etc/nginx/sites-available/elasticbeanstalk-nginx-docker-proxy-timeout.conf /etc/nginx/sites-enabled/elasticbeanstalk-nginx-docker-proxy-timeout.conf ; fi"
