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 thedocker_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"]
. -
dns
- (Optional, set of strings) Set of DNS servers. -
env
- (Optional, set of strings) Environmental 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". -
max_retry_count
- (Optional, int) The maximum amount of times to an attempt a restart whenrestart
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. -
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.
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.
