### [IM]MUTABLE /opt
|
|
## Some bootable images, like Fedora, have /opt symlinked to /var/opt, in order to
|
|
## make it mutable/writable for users. However, some packages write files to this directory,
|
|
## thus its contents might be wiped out when bootc deploys an image, making it troublesome for
|
|
## some packages. Eg, google-chrome, docker-desktop.
|
|
##
|
|
## Uncomment the following line if one desires to make /opt immutable and be able to be used
|
|
## by the package manager.
|
|
|
|
RUN rm /opt && mkdir /opt
|
|
|
|
### MODIFICATIONS
|
|
## make modifications desired in your image and install packages by modifying the build.sh script
|
|
## the following RUN directive does all the things required to run "build.sh" as recommended.
|
|
|
|
RUN --mount=type=bind,from=ctx,source=/,target=/ctx \
|
|
--mount=type=cache,dst=/var/cache \
|
|
--mount=type=cache,dst=/var/log \
|
|
--mount=type=tmpfs,dst=/tmp \
|
|
/ctx/build.sh && /ctx/cleanup.sh
|
|
|
|
### LINTING
|
|
## Verify final image and contents are correct.
|
|
RUN bootc container lint
