The java implementation of testcontainers provides useful preconfigured setups for certain databases.
They usually predefine an image and setup the special waiting strategy for that database.

This should be straight-forward for Go as well since there are many database clients around to do this.

I think I'll get started with a postgres setup.

Yep, this looks like a great idea. Can you write down some code here to help me understand how you imagine interacting with the postgres utils? probably just a fake test is enough

Should we start packaging this kind of solutions in a subpackage? Maybe a directory called canned?

	ctx := context.Background()
	mySql, err := canned.MySqlContainer(ctx, testcontainers.GenericContainerRequest{
		Started:          true,
	})
        mySql.GetClient() // returns a SQL client ready to be used

Having a testcontainers.GenericContainerRequest as a second parameter should give us all the flexibility we need because if something weird is required you can set your own request.

The MySql Container will attach the Log waiter and it will serve the right client

Mysql canned container
c8eeaa4 
Reference #19

I bootstrapped a mysql canned container.

```
ctx := context.Background()
c, err := MySQLContainer(ctx, MySQLContainerRequest{
        RootPassword: "root",
        Database:     "hello",
})
if err != nil {
        t.Fatal(err.Error())
}
defer c.Container.Terminate(ctx)
sqlC, err := c.GetDriver("root", "root", "hello")
if err != nil {
        t.Fatal(err.Error())
}
_, err = sqlC.ExecContext(ctx, "CREATE TABLE example ( id integer, data varchar(32) )")
if err != nil {
        t.Fatal(err.Error())
}
```

I'd be happy to write a Neo4j integration.

While this is being implemented, you might try using Gnomock which sets up databases and other services, and includes initial state setup features.

I am gonna this issue for now! As you can read in our documentation Golang is not really flexible when it comes to managing multiple modules in the same project and dependency management is still a pain.

https://golang.testcontainers.org/modules/

We decided to stay focused on the core library for now. If you decide to develop your module open a PR and link it in our documentation. We are happy to share it with the community but not to maintain it directly at this stage ❤️

Hello @gianarb, I'm wondering if you'd reconsider integrating database modules today?
What are the blockers in terms of multi-module management?
Couldn't each DB module have their go.mod and depend on the local main testcontainers module with a replace clause?

We started this PR, which could be the seed for modules: #618

It creates examples to be consumed by the website, but turning them into modules would be a matter of adjusting the templates.

Given #618 has been merged, we created #636, where you can find how to contribute new modules :)
