Camunder – a CLI for Camunda 8

Camunder is a CLI (command-line interface) for Camunda 8 that gives developers and operators faster, scriptable management of Camunda resources. It complements Camunda's Operate and Tasklist by enabling automation, bulk operations, and integration into existing workflows and pipelines.

While Operate and Tasklist cover most use cases via web interfaces, a CLI can be more efficient for automation, scripting, and quick operational tasks.

Camunder fills this gap with commands such as get, cancel, and delete, as well as specialized use cases like deleting active process instances by canceling it first or finding process instances with orphan parent process instances, which simplify recurring administration and maintenance of Camunda 8 process instances.

See Camunder in Action for more examples.

Highlights

Camunder simplifies various tasks related to Camunda 8, including these special use cases:

  • Delete active process instances by cancelling them first

    camunder delete pi --key <process-instance-key> --cancel

  • List process instances that are children (sub-processes) of other process instances

    camunder get pi --bpmn-process-id=<bpmn-process-id> --children-only

  • List process instances that are parents of other process instances

    camunder get pi --bpmn-process-id=<bpmn-process-id> --parents-only

  • List process instances that are children of orphan parent process instances
    (i.e., their parent process instance no longer exists)

    camunder get pi --bpmn-process-id=<bpmn-process-id> --orphan-parents-only

  • List process instances for a specific process definition (model) and its first version

    camunder get pi --bpmn-process-id=<bpmn-process-id> --process-version=1

  • List process instances with incidents

    camunder get pi --incidents-only

  • List process instances without incidents

    camunder get pi --no-incidents-only

  • Recursive search (walk) process instances with parent–child relationships

    • List all child process instances of a given process instance 
      camunder walk pi --mode children --start-key <process-instance-key>
    • List path from a given process instance to its root ancestor (top-level parent) 
      camunder walk pi --mode parent --start-key <process-instance-key>
    • List the entire family (parent, grandparent, …) of a given process instance (traverse up and down the tree) 
      camunder walk pi --mode family --start-key <process-instance-key>

  • List process instances in one line per instance (suitable for scripting)
    Works with all get commands.

    camunder get pi --one-line

  • List process instances just by their keys (suitable for scripting)
    Works with all get commands.

    camunder get pi --keys-only

  • …and more to come!

Upcoming features

  • bulk operations (e.g., delete multiple process instances by filter)
  • multiple Camunda 8 API versions support (currently 8.7, 8.8 to come)

Supported Camunda 8 APIs

  • 8.7.x

Configuration

Camunder uses Viper under the hood. Configuration values can come from:

  • Flags (--auth-client-id=...)
  • Environment variables (CAMUNDER_AUTH_CLIENT_ID=...)
  • Config file (YAML)
  • Defaults (hardcoded fallbacks)
Precedence

When multiple sources define the same setting, the highest-priority value wins:

Priority Source Example
1 (highest) Command-line flags --auth-client-id=cli-id
2 Environment vars CAMUNDER_AUTH_CLIENT_ID=env-id
3 Config file (YAML) auth.client_id: file-id
4 (lowest) Defaults http.timeout: "30s" (built-in)
Default configuration file locations

When searching for a config file, Camunder checks these paths in order and uses the first one it finds:

Priority Location Notes
1 ./config.yaml Current working directory
2 $XDG_CONFIG_HOME/camunder/config.yaml Skipped if $XDG_CONFIG_HOME is not set
3 $HOME/.config/camunder/config.yaml XDG default on Linux/macOS
4 $HOME/.camunder/config.yaml Legacy fallback
5 %AppData%\camunder\config.yaml (Windows only) %AppData% usually expands to C:\Users\<User>\AppData\Roaming
Example: C:\Users\Alice\AppData\Roaming\camunder\config.yaml
File format

Config files must be YAML. Example:

app:
  backoff:
    strategy: exponential
    initial_delay: 500ms
    max_delay: 8s
    max_retries: 0
    multiplier: 2.0
    timeout: 2m

auth:
  # OAuth token endpoint
  token_url: "http://localhost:18080/auth/realms/camunda-platform/protocol/openid-connect"

  # Client credentials (use env vars if possible)
  client_id: "camunder"
  client_secret: ""

  # Scopes as key:value pairs (names -> scope strings)
  # Do not define if not in use or empty
  scopes:
    camunda_api: "profile"
    operate_api: "profile"
    tasklist_api: "profile"

http:
  # Go duration string (e.g., 10s, 1m, 2m30s)
  timeout: "30s"

apis:
  # Base URLs for your endpoints
  camunda_api:
    base_url: "http://localhost:8080/v2"
  operate_api:
    base_url: "http://localhost:8081/v1"
  tasklist_api:
    base_url: "http://localhost:8082/v1"
Environment variables

Each config key can also be set via environment variable.
The prefix is CAMUNDER_, and nested keys are joined with _. For example:

  • CAMUNDER_AUTH_CLIENT_ID
  • CAMUNDER_AUTH_CLIENT_SECRET
  • CAMUNDER_HTTP_TIMEOUT
Security note

Sensitive fields such as auth.client_secret are always masked when the configuration is printed (e.g. with --show-config) or logged.
The raw values are still loaded and used internally, but they will never appear in output.

Example: Show effective configuration

You can inspect the effective configuration (after merging defaults, config file, env vars, and flags) with:

$ camunder --show-config
config loaded: /Users/adam.boczek/.camunder/config.yaml
{
  "Config": "",
  "App": {
    "Tenant": "",
    "Backoff": {

      "MaxRetries": 0,
      "Multiplier": 2,
      "Timeout": 120000000000
    }
  },
