Periodically check for new builds (artifacts) on CircleCI and install them locally in turn.
$ npm i cci-pingu
Installing this module adds a runnable file into your node_modules/.bin directory. If installed globally (with the -g option), you can run cci-pingu, otherwise you can run ./node_modules/.bin/cci-pingu.
To use the tool, you need to provide configuration file to it. You can copy the config template, edit it with actual values and you are good to go!
Config file is a JSON file with configuration object. The keys there have the following meaning:
| Name | Mandatory | Type | Default | Meaning |
|---|---|---|---|---|
| cci_url | string | https://circleci.com |
Base-URL of CircleCI. Use with self-hosted CircleCI installations. | |
| token | * | string | Your CircleCI API token that will be used when talking to CircleCI. Make sure you can access your project with this token. | |
| hosting | * | string | "github" or "bitbucket"; where you repo is hosted. | |
| organisation | * | string | The name of your github / bitbucket organisation (or user) under which the monitored project lives on CircleCI. | |
| project | * | string | The name of the project you'd like to watch and install locally. | |
| branch (1) | string | The project repository branch to monitor. | ||
| ignore_branch (1) | boolean | false |
If set to true, process builds from all branches. |
|
| workflows_job_name | string | When specified, the tool only looks for successful builds created as part of worflows by job with specified name. | ||
| artifacts | * | array of strings | List of artifact names that will be downloaded for successful build. Actually, it is list of artifact name substrings so that you can have "test" string in the artifacts array and it would match "test-1.2.3.tgz" artifact on CircleCI. |
|
| order_by | string | build_num |
When looking for the latest build, use this field in response to define the order (stop_time could be an interesting option for someone, too). |
|
| script | * | string | Filename of executable (typically script) that is able to install the artifacts locally. | |
| interval | integer | 60 |
When running in continuous mode, this number specifies the number of seconds between two consecutive checks on CircleCI. | |
| directory | string | /tmp |
The name of the directory in which build-related sub-directories storing the artifacts will be created. Make sure the directory exists and you have write permissions there. | |
| last | integer | 0 |
The number of the latest build successfully installed locally. This field is auto-updated by the tool after each successful installation. | |
| timeout | integer | 45 |
How long to wait for downloading an artifact (per-artifact-download setting). If downloading takes longer than provided number of seconds, it is considered failed. |
(1) One of "branch" and "ignore_branch" fields must be provided. If "ignore_branch" is set to false (default),
the "branch" field must be provided.
When the tool is started, it reads the configuration file specified as command-line argument. The structure of the configuration file is described above.
Unless you also pass specific CircleCI build number, the first thing cci-pingu does is figuring out what is the latest successful CircleCI build for given project on specified branch, or any branch in case ignore_branch is set to true. The order in which the latest successful build is looked up is defined with the order_by configuration option, and it is looked up in 100 lastest builds by build_num. In case workflows_job_name configuration option is provided, the successful builds are filtered on this specified workflows job name, other builds are not even considered.
This number (or number passed explicitly on command line as the build number to install) is then compared with the number of the latest CircleCI build installed locally (and stored in config file under last key).
If that build is already installed locally, it is either installed again (in case you used --install option), or the build is ignored. Then the tool either terminates (when started with --run-once or --install option), or (in continuous mode, which is the default operation mode) it waits interval seconds and tries again.
When the tool finds out that the latest CircleCI build (or the build provided on command line explicitly) is not installed locally, it retrieves the information about given build, including the artifacts of the build, and then compiles a list of artifacts that needs to be downloaded by comparing the list of artifacts listed in configuration file. As mentioned above, the list from configuration file is actually list of artifact name substrings, so when you have "test" in the artifacts array of the configuration file, and the build info indicates that there are two artifacts on CircleCI, "test-1.2.3.tgz" and "test-db-0.1.2.dump", then both the artifacts will match the substring and will be added to the list of artifacts to be donwloaded.
Once we know the list of the artifacts, the tool will create a new directory under directory from the config file. The name of the directory is build-<CCI-build-number>[.installation-attempt-number]. The installation attempt number is only used in case there already was some attempt to install the exact same build, but it failed for any reason.
After the directory is created, cci-pingu will download all the artifacts from the compiled list.
When all of the artifacts are downloaded into that directory, the tool starts executable (typically installation bash script) specified in the configuration file as script. This script must take two command line arguments, which are:
- the name of the directory into which the artifacts from CircleCI were downloaded, and
- the build number currently processed. It is expected that the script knows how to use the artifacts and what exactly to do with them to successfuly install them locally.
It might be a good idea to delete the directories from previous installations, and leave the last N artifact directories there, to keep the disk space occupied with these directories limited.
(ls -td build-* | head -n 5; ls -d build-*) | sort | uniq -u | xargs rm -rf
In case the return value of the installation script is 0, the installation is considered successful (in which case the last field of the configuration file is updated), otherwise it is considered failed.
In continuous mode (the default operation mode) the tool waits interval seconds and starts the check / installation again. If started with --run-once or when the CircleCI build number is passed explicitly on command line, then cci-pingu terminates.

$ git clone git@github.com:salsita/cci-pingu.git
$ cd cci-pingu
$ npm i
$ npm run build
$ npm run build
Generate version file, lint the ES6 source code, transpile the ES6 source code into dist directory, and verify the (transpiled) tests pass on the (transpiled) code.
$ npm run babel
Transpiles (using babel with .babelrc configuration file) the ES6 source code from lib directory and cci-pingu.js file into dist directory, that is referenced from binary bin/cci-pingu.
$ npm run gen-ver
Generate lib/version.js file exporting the current version of the tool, as taken from package.json itself.
$ npm run lint
Lint the (ES6) source code, using .eslintrc.json configuration file.
$ npm test
Verify the (transpiled) tests pass on the (traspiled) code. The test runner is mocha.
$ npm start
Start the tool in tool with config/default.json configuration file in debug mode. Note: the tool must be built first (so you need to run npm run build prior to npm start). Also, the default.json file needs to be updated with project-related information and CCI API token before starting the tool.
