Packer Task
Concord supports interaction with the infrastructure tool
Packer with the packer task as part of any
flow.
Usage
To be able to use the task in a Concord flow, it must be added as a dependency:
configuration:
dependencies:
- mvn://com.walmartlabs.concord.plugins:packer-task:1.32.3
This adds the task to the classpath and allows you to invoke it in any flow.
The task requires the process to run as a part of a Concord project.
Building Images
The build command executes packer build in the process’ working directory:
- task: packer
in:
command: build
template: packer.json
Parameters:
version- string value, version of Packer to use;url- string value, url of the Packer binary to use;debug- boolean value, iftruethe plugin logs additional debug information;force- boolean value, force a build to continue if artifacts exist, deletes existing artifacts;except- string list, run all builds and post-processors other than these;only- string list; build only the specified builds;onError- string value, if the build fails do:cleanuporabort;parallel- boolean value, iffalsedisable parallelization;parallelBuilds- int value, number of builds to run in parallel. 0 means no limit (default: 0);varFile- string value, JSON file containing user variables;template- string value, Packer template to use for building;extraVars- key value pairs, variables provided to thepackerprocess.
Input Variables
Input variables
can be specified using the extraVars parameter:
- task: packer
in:
command: build
extraVars:
aVar: "someValue"
nestedVar:
x: 123
The extraVars parameter expects regular java.util.Map<String, Object>
objects and supports all JSON-compatible data structures (nested objects,
lists, etc).
Specifying extraVars is an equivalent of running
packer build -var-file=/path/to/file.json.
Environment Variables
OS-level environment variables
can be specified using envars parameter:
- task: packer
in:
command: build
envars:
VERSION: 1.0
NAME: Concord
External Variable Files
Paths to an external files with variables can be added to plan or apply
actions using varFiles parameter:
- task: packer
in:
command: build
varFiles:
- "path/to/my-vars.json"
- "another/path/to/other/vars.json"
Paths must be relative to the current process’ ${workDir}.
