  required_providers {
    docker = {
      source  = "kreuzwerker/docker"
      version = "3.0.2"
    }
  }
}

provider "docker" {
    host = "tcp://${var.ssh_host}:2375"
}

resource "docker_image" "nginx" {

}

resource "docker_container" "nginx" {
  image = docker_image.nginx.latest

In the resource "docker_container" "nginx", change the image from

image = docker_image.nginx.latest

to

image = docker_image.nginx.image_id

Because the "docker_image" don`t output the attribute "latest", just "image_id".

See in the documentation
