documentclass not found

Steps to Recreate

1. `$ cd /srv/
2. $ sudo git clone https://github.com/overleaf/toolkit.git ./overleaf-toolkit
3. cd ./overleaf-toolkit && ./bin/init
4. ./bin/up

Behavior

Installed documentclass packages are not accessible from the service.
e.g. \documentclass{moderncv} returns LaTeX Error: File moderncv.cls' not found.`

After running tlmgr install moderncv and insuring it's installed with tlmgr list --only-installed it still won't recognize it's installed.
I've tried all the default compilers, pdfLaTeX, LaTeX, XeLaTeX, and LuaLaTeX.

This persists with other \docuemntclasss. No documentclass from CTAN works.

====== Warnings ======
! Detected SIBLING_CONTAINERS_ENABLED=false. When not using Sibling containers, users have full read and write access to the 'sharelatex' container resources (filesystem, network, environment variables) when running LaTeX compiles. Only use this mode in environments where all users are trusted and no isolation of users is required.
====== End ======

Reproduce the failure from the reported toolkit checkout using ./bin/init and ./bin/up, then inspect how the running service handles the tlmgr-installed moderncv package. Check the reported compiler variants and the configuration shown by /bin/doctor. Done means an installed CTAN documentclass is accessible to the service and the example compiles without a missing-file error.
