| literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently): | |
| :limit Numeric Type Column Size Max value | |
| 1 tinyint 1 byte 127 | |
| 2 smallint 2 bytes 32767 | |
| 3 mediumint 3 byte 8388607 | |
| nil, 4, 11 int(11) 4 byte 2147483647 | |
| 5..8 bigint 8 byte 9223372036854775807 | |
| Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers. |
The dokku-push action requires an SSH key with push access to the Dokku instance. Here's how to do that.
Replace APPNAME with the name of the app (e.g. this is a good idea to use the same name used on Dokku's).
We want each repo to have its own SSH key, so it's easier to rotate/invalidate them if required, without affecting all the repos. Let's generate a new key on your computer (see GitHub help):
