### Basic Docker Provider Configuration

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Configure the Docker provider for Terraform 0.13 and later, specifying the source, version, and host connection. This example also shows how to pull a Docker image and create a container.

```terraform
terraform {
  required_providers {
    docker = {
      source  = "kreuzwerker/docker"
      version = "4.0.0"
    }
  }
}

provider "docker" {
  host = "unix:///var/run/docker.sock"
}

# Pulls the image
resource "docker_image" "ubuntu" {
  name = "ubuntu:latest"
}

# Create a container
resource "docker_container" "foo" {
  image = docker_image.ubuntu.image_id
  name  = "foo"
}
```

### Provider Configuration Schema

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Configuration options for the Docker provider, including host connection and authentication settings.

```APIDOC
## Provider Configuration

### Description
Configuration settings for the Docker provider to establish connection to the Docker daemon and manage registry authentication.

### Parameters
#### Optional
- **ca_material** (String) - PEM-encoded content of Docker host CA certificate
- **cert_material** (String) - PEM-encoded content of Docker client certificate
- **cert_path** (String) - Path to directory with Docker TLS config
- **context** (String) - The name of the Docker context to use. Overrides the host if set.
- **disable_docker_daemon_check** (Boolean) - If true, the provider will not check if the Docker daemon is running.
- **host** (String) - The Docker daemon address
- **key_material** (String) - PEM-encoded content of Docker client private key
- **registry_auth** (Block Set) - Configuration for registry authentication
- **ssh_opts** (List of String) - Additional SSH option flags for ssh:// protocol

### Nested Schema for registry_auth
#### Required
- **address** (String) - Address of the registry

#### Optional
- **auth_disabled** (Boolean) - If true, the provider uses dummy credentials. Defaults to false.
- **config_file** (String) - Path to docker json file for registry auth. Defaults to ~/.docker/config.json.
- **config_file_content** (String) - Plain content of the docker json file for registry auth.
- **password** (String) - Password for the registry.
- **username** (String) - Username for the registry.
```

--------------------------------

### Registry Authentication with Config File

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Configure registry authentication for the Docker provider using a configuration file. Supports different registries and authentication methods, including username/password and config file content.

```terraform
provider "docker" {
  host = "tcp://localhost:2376"

  registry_auth {
    address     = "registry-1.docker.io"
    config_file = pathexpand("~/.docker/config.json")
  }

  registry_auth {
    address             = "registry.my.company.com"
    config_file_content = var.plain_content_of_config_file
  }

  registry_auth {
    address  = "quay.io:8181"
    username = "someuser"
    password = "somepass"
  }
}
```

```json
{
    "auths": {
        "repo.mycompany:8181": {
            "auth": "dXNlcjpwYXNz="
        },
        "otherrepo.other-company:8181": {}
    },
    "credsStore": "osxkeychain"
}
```

--------------------------------

### TLS Certificate Configuration for Docker Host

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Configure the Docker provider to connect to a Docker host using TLS. Specify certificate information either by providing a path to a directory or by directly providing the content of the CA, certificate, and key files.

```terraform
provider "docker" {
  host = "tcp://your-host-ip:2376/"

  # -> specify either
  cert_path = pathexpand("~/.docker")

  # -> or the following
  ca_material   = file(pathexpand("~/.docker/ca.pem")) # this can be omitted
  cert_material = file(pathexpand("~/.docker/cert.pem"))
  key_material  = file(pathexpand("~/.docker/key.pem"))
}
```

--------------------------------

### Registry Image Data Source

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Use the `docker_registry_image` data source to fetch information about a Docker image from a registry. This can be used without a running Docker daemon if `disable_docker_daemon_check` is set to true in the provider configuration.

```terraform
data "docker_registry_image" "quay" {
  name = "myorg/privateimage"
}
```

```terraform
data "docker_registry_image" "quay" {
  name = "quay.io:8181/myorg/privateimage"
}
```

--------------------------------

### Connect to Remote Docker Host via SSH

Source: https://registry.terraform.io/providers/kreuzwerker/docker/latest/docs

Configure the Docker provider to connect to a remote Docker host using the SSH protocol. Includes options for SSH connection and host key checking.

```terraform
provider "docker" {
  host     = "ssh://user@remote-host:22"
  ssh_opts = ["-o", "StrictHostKeyChecking=no", "-o", "UserKnownHostsFile=/dev/null"]
}
```
