Is it possible to use /bin/bash for all commands instead of /bin/sh ?
this is not possible, but you can put your build commands in a shell script and execute that with bash:
pipeline: build: image: ubuntu commands: - /bin/bash build.sh
The reason we use
/bin/sh is because it is, per the unix standard, available in every single docker image, where
/bin/bash is generally not available and therefore not an appropriate default.
Forgot to mention we are exposing the internals of the yaml compiler, so one could use a plugin to override the default behavior and use bin/bash. Tracking https://github.com/drone/drone/issues/1863
As a workaround one could do:
commands: - > bash -s <<SCRIPT env ls -lha SCRIPT
(that empty line before
SCRIPT is a MUST)
