Generate mysqlrouter.key without --bootstrap

[Jason Miele]

Our goal is to start MySQL-Router on new webserver when the webserver is instantiated. We see the MySQL-Router does not accept a password on the command line so we need a “mysqlrouter.key”. How may we create a key without calling the MySQL-Router’s “--bootstrap" option. For example, is it possible to create a “mysqlrouter.key” after the MySQL database starts up (the key is then stored and downloaded onto the webserver where MySQL-Router starts)?

Can we export the “mysqlrouter.key” from a MySQL database?

* Note, our MySQL database is running in an InnoDB cluster (instantiated with MySQL-Shell).
