CircleCI Reality Check

This repository is used to check for a proper installation of CircleCI Server. It implements a sample app that validates some basic CircleCI features in parallel workflows.

---

Installation

To install and run reality check on your CircleCI Server installation, follow these steps.

1. Fork this repository to the GitHub environment tied to your server installation. See here for more information.

2. Set up your repository project in your CircleCI Server installation.

3. Generate a personal api token - not a project token, and add it as an environment variable in your project with the name CIRCLE_TOKEN.

4. Determine the base URL of your install, including protocol, and remove the trailing slash and "app" subdomain if present. Add it as an environment variable in your project with the name CIRCLE_HOSTNAME.

   Note: As an example, if your dashboard is accessible at https://app.server.example.com/dashboard/ your CIRCLE_HOSTNAME is https://server.example.com

5. Set the environment variable in your project with the name CIRCLE_CLOUD_PROVIDER as either gcp, aws, or other. depending on your installation.

6. You can optionally set CIRCLE_WINDOWS_EXECUTOR to true in order to run a set of verification jobs for the windows execution environment. This requires a supported CircleCI Windows image, see instructions in CircleCI-Public/circleci-server-windows-image-builder.

7. Configure the following contexts and keys (their values can be anything). Docs on how to set up contexts can be found here.

Context Name	Environment Variable Key Name	Value
org-global	CONTEXT_END_TO_END_TEST_VAR	1
individual-local	MULTI_CONTEXT_END_TO_END_VAR	1

Example AWS Server Installation

# Project Environment Variables
CIRCLE_TOKEN=123456789-personal-access-token
CIRCLE_HOSTNAME=https://aws-server-install.example.com
CIRCLE_CLOUD_PROVIDER=aws
CIRCLE_WINDOWS_EXECUTOR=true # Optional, only if using a Windowws AMI

# org-global context environment variables
CONTEXT_END_TO_END_TEST_VAR=1

# individual-local context environment variables
MULTI_CONTEXT_END_TO_END_VAR=1

Example GCP Server Installation

# Project Environment Variables
CIRCLE_TOKEN=123456789-personal-access-token
CIRCLE_HOSTNAME=https://gcp-server-install.example.com
CIRCLE_CLOUD_PROVIDER=gcp
CIRCLE_WINDOWS_EXECUTOR=true # Optional, only if using a Windows AMI

# org-global context environment variables
CONTEXT_END_TO_END_TEST_VAR=1

# individual-local context environment variables
MULTI_CONTEXT_END_TO_END_VAR=1

Running Reality Check

Once installed, to run reality check, make any commit to the default branch of your forked repository. If installed correctly, your CircleCI Server Installation will pick up the commit and build it in parallel workflows.

git commit --allow-empty -m "Trigger Build, Empty commit" && git push

Reality Check Workflows

Descriptions of the three workflows follow.

resource_class workflow

Tests all known resource_class options—queries the CircleCI API to verify that jobs ran with the requested resources.

Prerequisites

• Your Nomad client instances must be large enough to accommodate these resource classes — see our Configuration Reference for details on the available resource classes and our server docs about sizing your Nomad client instances.
• The base URL of your CircleCI installation (e.g. https://circleci.com) must be specified via a CIRCLE_HOSTNAME project environment variable
• A personal API token (see CIRCLE_HOSTNAME/account/api URL endpoint) must be stored as a CIRCLE_TOKEN project environment variable

VM service workflow

Tests the functionality of the machine executor, Remote Docker Environment, and Docker Layer Caching.

Features workflow

• Tests ability to save and restore caches
• Tests writing to and reading from workspaces
• Tests the default org-global context (NOTE: needs a key called CONTEXT_END_TO_END_TEST_VAR to exist in a context called org-global)
• Tests multiple contexts (NOTE: needs a key called MULTI_CONTEXT_END_TO_END_VAR to exist in a context called individual-local)
• Tests upload/storage of artifacts and test results

GCP Jobs Workflow

Tests android machine images on Google Cloud Platform. First checks if the environment is configured for GCP with the CIRCLE_CLOUD_PROVIDER environment variable.

Prerequisites

You will need to have your CIRCLE_TOKEN environment variable set to a personal access token, and will need your CIRCLE_CLOUD_PROVIDER set to gcp in lower-case. You must also have nomad clients configured, and your vm-service configured.

AWS Jobs Workflow

Tests ARM based images on AWS. First checks if the environment is configured for AWS with the CIRCLE_CLOUD_PROVIDER environment variable.

Prerequisites

You will need to have your CIRCLE_TOKEN environment variable set to a personal access token, and will need your CIRCLE_CLOUD_PROVIDER set to aws in lower-case. You must also have nomad clients configured, and your vm-service configured.
