As Mastodon temporaliry saves uploaded content to memory and disk (if
/tmp is a disk), unlimiting client max body size makes the server
vulnerable to DoS attack.
Without headless a lot of (for a server) unneeded dependencies needs be installed (on Debian stretch), like icon sets and x11-utils. Elasticsearch works without problems when you only install openjdk-8-jre-headless (that has much less dependencies).
Consolidated all basic configuration steps for the ideal case to top of document, moved all memory-related and "advanced" configuration to bottom. Removed remote Elasticsearch config from document entirely and replaced it with a link to ES documentation on the topic instead.
db:setup is used in all guides except Docker Guide, which uses db:migrate
to create the database. db:setup is actually superior over db:migrate for
the purpose in terms of performance and compatibility.
db:setup is performant because it does not perform redundant migrations.
db:migrate, on the other hand, executes migration code which will be
dismissed by later migrations. db:migrate also waits for seconds to allow
to interrupt migrations if it is not favorable to run them on a running
server, but db:setup is obviously executed on a instance which is not
running yet, and the wait is unnecessary.
db:migrate has a compatibility issue. It requires a compatibility layer
to keep it working, and such one may be broken, or not provided by
dependencies such as Paperclip.
This commit replaces db:migrate with db:setup in the building guide. The
procedure cannot be applied to migration from an older release, where
the old procedure could, but it is not problematic because it has
dedicated Updating section.
* Clarify Docker instructions for prebuilt images
Made clear there are two options for getting the Docker image: pulling the prebuilt image, or building your own. Using a prebuilt image is easier for anyone who hasn't made code changes on their instance.
* Fix errors in Docker prebuilt image instructions
* OpenBSD-specific development guide
The GNU/Linux setup works well but there are some OpenBSD-specific
considerations around default compilers, discovering third-party
libraries, and linker warnings.
* Fix typos
- Be a little clearer about what's going on at each step.
- Give more detailed update instructions (and be smarter about selecting the "latest" tag).
- Mention the `VAPID_*_KEY` variables.
This gives some advice on getting started with an email service guide, including specifics on the process and caveats of the various free services people recommend, as well as a short command in the Rails console that helps a user test this out.
