docker_container

Manages the lifecycle of a Docker container.

Example Usage

# Start a container
resource "docker_container" "ubuntu" {
  name = "foo"
  image = "${docker_image.ubuntu.latest}"
}

# Find the latest Ubuntu precise image.
resource "docker_image" "ubuntu" {
  name = "ubuntu:precise"
}

Argument Reference

The following arguments are supported:

• name - (Required, string) The name of the Docker container.

• image - (Required, string) The ID of the image to back this container. The easiest way to get this value is to use the docker_image resource as is shown in the example above.

• command - (Optional, list of strings) The command to use to start the container. For example, to run /usr/bin/myprogram -f baz.conf set the command to be ["/usr/bin/myprogram", "-f", "baz.conf"].

• entrypoint - (Optional, list of strings) The command to use as the Entrypoint for the container. The Entrypoint allows you to configure a container to run as an executable. For example, to run /usr/bin/myprogram when starting a container, set the entrypoint to be ["/usr/bin/myprogram"].

• user - (Optional, string) User used for run the first process. Format is user or user:group which user and group can be passed literraly or by name.

• dns - (Optional, set of strings) Set of DNS servers.

• dns_opts - (Optional, set of strings) Set of DNS options used by the DNS provider(s), see resolv.conf documentation for valid list of options.

• dns_search - (Optional, set of strings) Set of DNS search domains that are used when bare unqualified hostnames are used inside of the container.

• env - (Optional, set of strings) Environment variables to set.

• labels - (Optional, map of strings) Key/value pairs to set as labels on the container.

• links - (Optional, set of strings) Set of links for link based connectivity between containers that are running on the same host.

• hostname - (Optional, string) Hostname of the container.

• domainname - (Optional, string) Domain name of the container.

• restart - (Optional, string) The restart policy for the container. Must be one of "no", "on-failure", "always", "unless-stopped".

• max_retry_count - (Optional, int) The maximum amount of times to an attempt a restart when restart is set to "on-failure"

• must_run - (Optional, bool) If true, then the Docker container will be kept running. If false, then as long as the container exists, Terraform assumes it is successful.

• ports - (Optional, block) See Ports below for details.

• host_entry - (Optional, block) See Extra Hosts below for details.

• privileged - (Optional, bool) Run container in privileged mode.

• publish_all_ports - (Optional, bool) Publish all ports of the container.

• volumes - (Optional, block) See Volumes below for details.

• memory - (Optional, int) The memory limit for the container in MBs.

• memory_swap - (Optional, int) The total memory limit (memory + swap) for the container in MBs. This setting may compute to -1 after terraform apply if the target host doesn't support memory swap, when that is the case docker will use a soft limitation.

• cpu_shares - (Optional, int) CPU shares (relative weight) for the container.

• log_driver - (Optional, string) The logging driver to use for the container. Defaults to "json-file".

• log_opts - (Optional, map of strings) Key/value pairs to use as options for the logging driver.

• network_mode - (Optional, string) Network mode of the container.

• networks - (Optional, set of strings) Id of the networks in which the container is.

• destroy_grace_seconds - (Optional, int) If defined will attempt to stop the container before destroying. Container will be destroyed after n seconds or on successful stop.

Ports

ports is a block within the configuration that can be repeated to specify the port mappings of the container. Each ports block supports the following:

• internal - (Required, int) Port within the container.
• external - (Required, int) Port exposed out of the container.
• ip - (Optional, string) IP address/mask that can access this port.
• protocol - (Optional, string) Protocol that can be used over this port, defaults to TCP.

Extra Hosts

host_entry is a block within the configuration that can be repeated to specify the extra host mappings for the container. Each host_entry block supports the following:

• host - (Required, int) Hostname to add.
• ip - (Required, int) IP address this hostname should resolve to..

This is equivalent to using the --add-host option when using the run command of the Docker CLI.

Volumes

volumes is a block within the configuration that can be repeated to specify the volumes attached to a container. Each volumes block supports the following:

• from_container - (Optional, string) The container where the volume is coming from.
• host_path - (Optional, string) The path on the host where the volume is coming from.
• volume_name - (Optional, string) The name of the docker volume which should be mounted.
• container_path - (Optional, string) The path in the container where the volume will be mounted.
• read_only - (Optional, bool) If true, this volume will be readonly. Defaults to false.

One of from_container, host_path or volume_name must be set.

Attributes Reference

The following attributes are exported:

• ip_address - The IP address of the container as read from its NetworkSettings.
• ip_prefix_length - The IP prefix length of the container as read from its NetworkSettings.
• gateway - The network gateway of the container as read from its NetworkSettings.
• bridge - The network bridge of the container as read from its NetworkSettings.
