Base Configuration#

Each deployment tool is traditionally controlled with a set of CLI arguments. Instead of defining arguments within your pipeline configuration, they can instead either be defined with environment variables or in a bitops.config.yaml file. While the core schema for a bitops.config.yaml file is common between tools, the specific properties and environment variable equivalents vary from tool to tool.

For more information on tool configuration, see plugins.

Base Schema#

All bitops.config.yaml files share the following structure

  cli: {}
  options: {}

  • $tool - identifies the deployment tool
  • cli - object that contains CLI arguments
  • options - an object that offers additional control over how a tool executes

Environment Variable Defaulting#

Plugin environment variables are automatically mapped to the bitops.config.yaml keys. This means that you can use the same environment variable names as in the plugin config. For example, if you want to override the ansible.cli.skip-tags value, you can use the BITOPS_ANSIBLE_SKIP_TAGS environment variable. In this case, BITOPS is the prefix, ANSIBLE is the plugin name, and SKIP_TAGS is the key name (note hypens are replaced with underscores).

The precedence order is: ENV vars > bitops.config.yaml values > bitops.config.schema.yaml defaults. This way, ENV variables specified by user are taking highest precedence over config values and defaults. We recommend using them dynamically in CI/CD pipelines to control the deployment based on condition (PR run, branch, etc) or manually passing to the the BitOps docker container.

OpsRepo configuration override#

BitOps configuration is overridable by OpsRepo level bitops.config.yaml configuration files. The OpsRepo BitOps configuration file is expected to be found in the OpsRepo/ENVIRONMENT directory.

These configuration files use the same schema as the bitops/bitops.schema.yaml, all values in the bitops schema can be configured from the OpsRepo level bitops.config.yaml. The bitops/bitops.config.yaml file sets the default run pattern for bitops and can be used as an example to write OpsRepo bitops configuration.

Example OpsRepo config file path

|___ Dev/
|       bitops.config.yaml

Example BitOps configuration override

      plugin: terraform
      plugin: terraform
      plugin: ansible

Arbitrary Environment Variables#

During the docker run command, you can specify an ENV var and it will be accessible during all processing stages of BitOps. This is useful for passing in secrets or other custom values used in the workflows.

Common Configuration#

There are some global configuration options that are shared among all tools and cloud providers during a BitOps run. These are set via environment variables

Property Environment Variable Description Default Required
environment BITOPS_ENVIRONMENT Each BitOps run is done against a single environment. This property tells BitOps which environment to run. For more information on environments, see Operations Repo Structure. Yes
kubeconfig_base64 KUBECONFIG_BASE64 Base64 encoded kubeconfig file. Allows deployment tools to interact with a Kubernetes cluster. null No
