Shell usage in dockerfile | 2019-02-04 | How to use a proper shell in a dockerfile |
|
The problem
The default shell is [“/bin/sh”, “-c”]
, which doesn't handle pipe fails when chaining commands.
The fix
To process errors when using pipes use this :
{{< highlight sh >}} SHELL ["/bin/bash", "-eux", "-o", "pipefail", "-c"] {{< /highlight >}}
