>
> The localstack container is used to mock aws services so tests can hit a mock
> endpoint. When we start the container, it occasionally fails with the
> exception: {{IOException - closed before protocol could be determined.}} This
> is what happens whenever we make a request (e.g. read from mock s3) prior to
> the container being ready**. A similar issue was resolved in Kinesalite by
> increasing the timeout from 1s to 10s, but Localstack is a larger box. In
> #18887 we increased the timeout to 30s, which would be sufficient for it to
> start. However, it would be better to use [this
> strategy|[https://ignas.me/tech/waiting-localstack-s3-start/]] to know sooner.
> ** This is a known limitation, please see issue
> [#1202|https://github.com/localstack/localstack/issues/1202] in
> Localstack/localstack or this [blog
> post|https://ignas.me/tech/waiting-localstack-s3-start/].
