Why I can not use a 5.7 nor a 5.6 mysql docker image instead of mysql 8 with terraform in windows? - mysql

Question

I am testing a mysql_database inside a docker_container.mysql using terraform in windows, but every time I try to use an image different from mysql:8 inside the docker_image.mysql used by docker_container.mysql, terraform takes 5 minutes to create the mysql_database resource and throws the following error:
Error: Could not connect to server: dial tcp 127.0.0.1:3306: connectex: No connection could be made because the target machine actively refused it.
on main.tf line 33, in resource "mysql_database" "test":
33: resource "mysql_database" "test" {
And here is main.tf:
provider "docker" {
host = "npipe:////.//pipe//docker_engine"
}
resource "docker_image" "mysql" {
name = "mysql:8"
//keep_locally = true
}
resource "docker_container" "mysql" {
name = "mysql"
image = docker_image.mysql.latest
restart = "always"
env = [
"MYSQL_ROOT_PASSWORD=root"
]
volumes {
volume_name = "mysql-vol"
container_path = "/var/lib/mysql"
}
ports {
internal = 3306
external = 3306
}
}
provider "mysql" {
endpoint = "127.0.0.1:3306"
username = "root"
password = "root"
}
resource "mysql_database" "test" {
name = "test"
depends_on = [docker_container.mysql]
}
I am testing mysql image tags shown at https://hub.docker.com/_/mysql, specifically 5.6, 5.7 and 8, but only using mysql:8 seems to work Is there an other way in which I should reference those mysql image tags?

Answer 1

I tried to verify the issue, and I observed the same error as yours only for mysql 5.7 and 5.6 when you keep the same volumes.
After removing the following section from the terraform script
volumes {
volume_name = "mysql-vol"
container_path = "/var/lib/mysql"
}
and removing existing mysql docker images, mysql 5.6, mysql 5.7 and 8 worked as expected.
Btw, the error leading to failed connection was:
ERROR 2013 (HY000): Lost connection to MySQL server at 'handshake: reading initial communication packet', system error: 11
