This changes the default for
src batch exec
(used by SSBC) to run all step containers as root, and adds a flag tosrc batch apply
andsrc batch preview
to optionally do the same thing.Fixes sourcegraph/sourcegraph#41836.
Test plan
Tested with client and server side batch changes and a batch spec that outputs
id
into a file, with a container image that does not run as root by default (specifically,haproxy:alpine
).
