Local Exec

The exec_local resource allows the execution of arbitrary commands and scripts on the local machine. The command runs in the local user space, and has access to all the environment variables that the user executing shipyard run has access too. Additional environment variables, and the working directory for the command can be specified as part of the resource stanza.

Log files for exec_local are written to $HOME\.shipyard\logs\[name].log

Minimal Example

The following example will run the command consul services register ./config/redis/hcl and will wait for it to complete. If the command takes longer than 30s to complete, it will be automatically killed.

exec_local "exec_standalone" {  cmd = "consul"  args = [    "services",    "register",    "./config/redis.hcl"  ]
  env {    key = "CONSUL_HTTP_ADDR"    value = "http://consul.container.shipyard.run:8500"  }
  timeout = "30s"}

Daemon Mode

The following example runs the command consul agent -dev and immediately returns leaving the command to run as a daemon which is not terminated when the shipyard run command completes.

Daemons either exit on their own or are killed when running shipyard destroy.

exec_remote "exec_standalone" {  cmd = "consul"  args = [    "agent",    "-dev",  ]
  daemon = true}

Parameters

depends_on

Type: []string
Required: false

Depends on allows you to specify resources which should be created before this one. In the instance of a destruction, this container will be destroyed before resources in.

command

Type: string
Required: false

Command allows you to specify a command to execute when starting a container.

args

Type: []string
Required: false

Arguments passed to the command to execute when starting a container. For example, to execute a command which installs Shipyard the following command and arguments can be used.

cmd = "curl"
args = [    "https://shipyard.run/install",    "|",    "bash",    "-s"]

working_directory

Type: string
Required: false

Set the working directory where the command will be executed.

environment

Type: key_value
Required: false

An environment stanza allows you to set environment variables which will be used by the command.

env {  key = "PATH"  value = "/usr/local/bin"}

env_vars

Type: map[string]string
Required: false

An env_vars parameter allows you to set environment variables for the command.

env_var = {  "abc" = "123",  "foo" = "bar"}
### timeout**Type: string**  **Default: 30s****Required: false**
Timeout allows you to specify a maximum duration that a script can run for, it is specified using Go's duration syntax.If the timeout period elapses before the command completes Shipyard will kill the command and fail the `run`.
When the `daemon` parameter is set to `true`, timeout is ignored.
```javascripttimeout = "30s" # 30 second timeout
timeout = "3m" # 3 minute timeout

daemon

Type: boolean
Default: false Required: false

Daemon allows you to tell Shipyard to run the command as an unattended process. When this attribute is set to true Shipyard will start the process but will not wait for it to complete. Unless the script or command exits it will continue to run until the blueprint is destroyed with the shipyard destroy command.
