error when trying to build with a openjdk:8-jre image

Hello @ChadLei, I had the same issue here but it was because I was executing the command with sh like this:

$ sh ./wait-for-it.sh www.google.com:80

I removed the sh command and it worked for me.

$ ./wait-for-it.sh www.google.com:80

[ChadLei]

great tip thanks!

I have a same problem.
run sh ./wait-for-it.sh www.google.com:80 on openjdk:8-jre image.

Why I mast run sh command.
Because there is not bash command

I got the exact same problem with alpine:3.7, when running

sh wait-for-it.sh www.google.com:80

I don't have bash installed, so the fix of @baptooo is not working for me.
AS mentioned here the parenthesis are for executing sub-processes in bash.
Any thoughts about how to solve that problem?

[warthur1214]

@HasBert You need install bash. Try this:

apk add --no-cache bash
./wait-for-it.sh www.google.com:80

[identitymonk]

it works but the correct command is:
apk add --no-cache bash

There was a typo in @warthur1214 suggestion cause of two add

[warthur1214]

@identitymonk sorry to puzzle you. I forgot to remove 'add'

[mikaelengstrom]

Would it not be cleaner to make the script compatible with sh rather than enforce bash on minimalistic containers? Any thoughts?

[srdecny]

If you get this error while being sure you're running this with bash, make sure the first line of the script contains the shebang. (I put a link to the repo as a comment as the first line 😅 )

maybe this will work: #80

maybe this will work: #80

The ash script worked!
