title: NTP time sync service on AWS ECS
body: <p>I'm architecting infrastructure via AWS.</p>
  
  <p>To deploy docker-compose, I used ECS.</p>
  
  <p>For resolve time sync issue, I found some interesting article. (<a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html</a>)</p>
  
  <p>It looks very simple if just launch EC2 instance.</p>
  
  <p>After read that article, I found some issue on my case.</p>
  
  <p>Docker container is running on EC2 instance. </p>
  
  <p>So, I just set NTP to my EC2 instance only?</p>
  
  <p>Or, have to set NTP for my docker container too?</p>
  
  <p>I can't find any document related this issue.</p>
  
  <p>Any suggestion, will be a lot of help.</p>
  
  <p>Thanks.</p>
