waldronlab/wallabe-devel repository overview

⁠wallabe-devel

The wallabe-devel Docker container is a custom container built on top of the waldronlab/bioconductor:devel container. It differs in two principle ways: 1) the /usr/local/lib/R/site-library directory is writeable to all users and 2) host user directories are mounted into the container with the correct permissions and ownership (provided the invocation below is followed).

The first item above is achieved through revisions to the s6 overlay /etc/fix-attrs.d/00-runscripts ownership and permissions script. The second item above is achieved by invoking the container with a bash script as follows and then correcting ownership and permissions with another s6 overlay script at /etc/cont-init.d/userconf during the init process. It is necessary to change the user directory ownership and permissions during the init process, rather than in the /etc/fix-attrs.d/00-runscripts script, because user directories are not mounted (and their structure cannot be assumed prior to) the starting to the container.
