Remove wait-for-it.sh from container

[RopoMen]

Hi,

Could you please remove wait-for-it.sh script from Dockerfile and instead

1. add it in to repository and mount it inside the container before tests
2. Or download it inside command before tests

https://github.com/buildkite/docker-puppeteer/blob/master/example/docker-compose.integration-tests.yml#L10

It does not look good when something is downloaded from random place. And in this case it is only needed in tests.

Br, Markku

Hi there,

I've only recently started using this package for and I must say, I will be using wait for it in my local environment, so it is a convenience to have it bundled.

On the other hand, it should be maybe pointed out in the Readme, however, the Dockerfile is so small, it takes a second to read through - which is always recommended.
