You have seen in this previous post, that since 8.0.17, it’s now possible to query the MySQL Router using its REST API.

Additionally, we also saw in this post, that since 8.0.17, we are now able to write extensions to MySQL Shell using the Extension Framework.

Let’s combine both and see how we can integrate the MySQL Router’s REST API in the Shell.

I’ve created an extension in ext.router that creates a MySQL Router Object.

The new extension, as a method to create the object:

This is an example that illustrates how to create a MySQL Router Object, as you can see you can pass the password directly as parameter but it’s not recommended in interactive mode. It’s …

Since MySQL 8.0.16, the Router as the possibility to launch an internal webserver (see Jan’s blog post).

Even if this webserver could serve static files, it was the first piece of a much more interesting solution that is now available since 8.0.17.

It’s possible now to query the MySQL Router via its REST API and get a lot of useful information.

Setup

Let’s first configure our MySQL Router to take advantages of this new feature. In this example, I will add the following lines to /etc/mysqlrouter/mysqlrouter.conf that I created using the --bootsrapcommand line argument:

[http_server]
port=8080

[rest_api]

[rest_router]
require_realm=somerealm

[rest_routing]
require_realm=somerealm …

InnoDB Cluster was released as GA a few weeks ago. I remember the initial announcement of the product at OOW 2016, promising a seamless solution for replication and high availability with great ease of use. I was a bit disappointed to see that, at GA release time, the InnoDB Cluster is a patchwork of three separate products (Group Replication, MySQL Router, MySQL Shell) which the users have to collect and install separately.

Given this situation, I was very pleased when Matthew Lord published Docker-InnoDB-Cluster, an image for Docker that contains everything you need to get the system up and running. The …
