Hi folks, Having just built the awesome new dashboard code (https://github.com/ceph/ceph/pull/20103) in my dev environment for the first time, I'll share my notes... When building on Ubuntu 16.04, which does not have a recent enough node.js for the build -- had to get one from an external source. It looks like Fedora and EPEL do have more recent ones. Not sure if there is a sufficiently trusted third party Ubuntu repo to add to install_deps.sh. My fedora 26 machine had a sufficiently recent node/npm, so building there was simpler. Just had to install the python2-bcrypt package (in addition to what is already covered in install_deps). The frontend build only takes 25 seconds, which I think is pretty good. The resulting dist/ dir is 18M at the moment, which is very similar to the existing dashboard static files size. I would suggest we can decrease that a bit by restricting the font formats included: by default we're getting eog/svg/ttf output, but we probably only need WOFF. I didn't need a virtualenv or any pip-installed things to run the dashboard in development (presumably would have needed that to run unit tests on the backend python code). Detailed notes below. Cheers, John On Ubuntu 16.04 (aka senta04) ============= Had to symlink /usr/bin/nodejs to /usr/bin/node (one of the dependencies depends on it) The distro comes with node 4.2.6. The dashboard_v2 code requires node >= 6.9.0 (per tmelo) -- that isn't being explicitly checked, so if your node is old then you just get a nasty syntax error during "npm run build". Angular CLI depends on node >= 6.9.0 and npm >= 3 (according to its README). Repo with a more recent node is here: curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - This is linked from the nodejs official page, but I have no idea of provenance beyond that. If you had already tried "npm run build" with an older node before installing the newer one, do a "npm rebuild node-sass" after installing the new node before trying to build dashboard frontend again. Had to install python-bcrypt. Fedora 26 (aka my laptop) ======== This distro appears to come with node 6.12. dnf install python2-bcrypt -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
