Preparing to deploy

Background information:

• https://bugs.torproject.org/23947#comment:8
• https://help.torproject.org/tsa/doc/static-sites/
• https://help.torproject.org/tsa/doc/ssh-jump-host/

You need to be in LDAP group "snowflake" and have set up an SSH key with your LDAP account. In your ~/.ssh/config file, you should have something like:

Host staticiforme
HostName staticiforme.torproject.org
User <your user name>
ProxyJump people.torproject.org
IdentityFile ~/.ssh/tor

Deploying

npm run build

Do a "dry run" rsync with -n to check that only expected files are being changed. If you don't understand why a file would be updated, you can add the -i option to see the reason.

rsync -n --chmod ug=rw,D+x --perms --delete -crv build/ staticiforme:/srv/snowflake.torproject.org/htdocs/

If it looks good, then repeat the rsync without -n.

rsync --chmod ug=rw,D+x --perms --delete -crv build/ staticiforme:/srv/snowflake.torproject.org/htdocs/

Then run the command to copy the new files to the live web servers:

ssh staticiforme 'static-update-component snowflake.torproject.org'

Parameters

With no parameters, snowflake uses the default relay snowflake.freehaven.net:443 and uses automatic signaling with the default broker at https://snowflake-broker.freehaven.net/.
