I am using the sbt-native-packager plugin to generate a Docker image for a Scala project. The project requires a specific package libnetcdf.so to be installed on the image.
I am using the below configuration on my build.sbt
dockerCommands ++= Seq(
ExecCmd("RUN","sudo","apt-get","update"),
ExecCmd("RUN","sudo","apt-get","install","-y","libnetcdf-dev")
)
However when generating/building the image using sbt docker:publishLocal I get the below errors.
[error] #18 [mainstage 6/7] RUN ["sudo", "apt-get", "update"]
[error] #18 0.358 runc run failed: unable to start container process: exec: "sudo": executable file not found in $PATH
[error] #18 ERROR: process "sudo apt-get update" did not complete successfully: exit code: 1

Cannot find the right way to install a dependency using the dockerCommands
Any help/pointers will be greatly appreciated.
EDIT:
Silly enough, it turns the default base image was not a Debian-based distro. Replaced with an Ubuntu docker image and it all worked as intended. As per @Gaël J response it doesn't need "sudo".
Was able to figure the distribution using the below.
ExecCmd("RUN","cat","/etc/os-release")
Remove sudo.
ExecCmd("RUN","apt-get","update")
It doesn't exist in the image as the error says.
And moreover you don't need it because the build is likely done as root user, and only switched to a non-root user at the end. (Worth checking that though, I don't know what the SBT plugin generates by default).
