# Environment Variables # Environment Variables Flowpipe supports environment variables to allow you to change its default behavior. These are optional settings - You are not required to set any environment variables. Note that plugins may also support environment variables, but these are plugin-specific - refer to your plugin's documentation on the [Flowpipe Hub](https://hub.flowpipe.io/) for details. ## Flowpipe Environment Variables | Command | Default | Description |-|-|- | [FLOWPIPE_BASE_URL](/docs/reference/env-vars/flowpipe_base_url) | `http://localhost:7103` | Set the base URL to use for [triggers](/docs/flowpipe-hcl/trigger) and [integrations](/docs/reference/config-files/integration). This is the base URL that Flowpipe advertises when it interacts with external systems to allow them to call back to Flowpipe. | [FLOWPIPE_CONFIG_PATH](/docs/reference/env-vars/flowpipe_config_path) | `.:$FLOWPIPE_INSTALL_DIR/config` | Set the search path for [configuration files](/docs/reference/config-files). `FLOWPIPE_CONFIG_PATH` accepts a colon-separated list of directories. | [FLOWPIPE_HOST](/docs/reference/env-vars/flowpipe_host) | none | Set the remote Flowpipe API host to connect to. This allows you to run Flowpipe commands against a flowpipe host instead of the current working directory / mod location. | [FLOWPIPE_INSTALL_DIR](/docs/reference/env-vars/flowpipe_install_dir) | `~/.flowpipe` | Set the installation directory for flowpipe. Internal flowpipe files will be written to this path. | [FLOWPIPE_LISTEN](/docs/reference/env-vars/flowpipe_listen) | `network` | Specifies the IP addresses on which `flowpipe server` will listen for connections from clients. Currently supported values are `local` (localhost only) or `network` (all IP addresses). | [FLOWPIPE_LOG_LEVEL](/docs/reference/env-vars/flowpipe_log_level) | off | Set the logging output level | [FLOWPIPE_MAX_CONCURRENCY_CONTAINER](/docs/reference/env-vars/flowpipe_max_concurrency_container) | `25` | Set the maximum number of `container` step instances that can execute concurrently across all pipeline instances. | [FLOWPIPE_MAX_CONCURRENCY_FUNCTION](/docs/reference/env-vars/flowpipe_max_concurrency_function) | `50` | Set the maximum number of `function` step instances that can execute concurrently across all pipeline instances. | [FLOWPIPE_MAX_CONCURRENCY_HTTP](/docs/reference/env-vars/flowpipe_max_concurrency_http) | `500` | Set the maximum number of `http` step instances that can execute concurrently across all pipeline instances. | [FLOWPIPE_MAX_CONCURRENCY_QUERY](/docs/reference/env-vars/flowpipe_max_concurrency_query) | `50` | Set the maximum number of `query` step instances that can execute concurrently across all pipeline instances. | [FLOWPIPE_MEMORY_MAX_MB](/docs/reference/env-vars/flowpipe_memory_max_mb) | `1024` | Set a soft memory limit for the `flowpipe` process. | [FLOWPIPE_MOD_LOCATION](/docs/reference/env-vars/flowpipe_mod_location) | current working directory | Set the workspace working directory | [FLOWPIPE_PORT](/docs/reference/env-vars/flowpipe_port) | `7103` | Specifies the TCP port on which `flowpipe server` will listen for connections from clients. | [FLOWPIPE_TELEMETRY](/docs/reference/env-vars/flowpipe_telemetry) | `info` | Set the level of telemetry data to collect and send | [FLOWPIPE_UPDATE_CHECK](/docs/reference/env-vars/flowpipe_update_check)| `true` | Enable/disable automatic update checking | [FLOWPIPE_WORKSPACE](/docs/reference/env-vars/flowpipe_workspace) | `default` | Set the Flowpipe workspace . This can be named workspace from `workspaces.fpc` or a remote Flowpipe Cloud workspace | [PIPES_INSTALL_DIR](/docs/reference/env-vars/flowpipe_base_url) | `~/.pipes` | Set the installation directory for files used with [Turbot Pipes](https://turbot.com/pipes/docs), such as login tokens.
