helix export¶
Export a flow project in one of three formats: a bundled YAML (every
imports: and ${file:...} resolved into one self-contained file),
a .env template enumerating every ${VAR} referenced, or a
multi-stage Dockerfile that builds and runs the project.
Usage¶
Flags¶
| Flag | Default | Description |
|---|---|---|
--format=FMT |
docker |
Output format: yaml (alias bundle), env, or docker. |
--output=PATH |
stdout | Write to PATH instead of stdout. |
The first non-flag argument is the flow file.
Formats¶
--format=docker¶
Emits a multi-stage Dockerfile that builds the Helix binary from source
and ships an image containing just /helix and /flow.yaml. Exposes
ports 8080 (http-server), 8081 (health), and 9090 (metrics/management).
The COPY line names the flow file by its basename, so the generated
Dockerfile expects to be built from the project root.
--format=yaml (alias bundle)¶
Loads the flow with dsl.LoadYAMLFull, which resolves every
imports: and ${file:...} include, then re-marshals the resolved
graph as a single YAML document. The output preserves the original
helix: config, declared connectors, agents, and workflows, but
flattens the imports tree so the result is portable.
Prints Exported bundle to PATH (N bytes, M routes) on success when
writing to a file.
--format=env¶
Scans the flow file and every glob-resolved imports: target for
${VAR} and ${VAR:-default} references, deduplicates them, and
emits a sorted .env template. Defaults are recorded as
# Default: <value> comment lines above the key. Two reserved
namespaces are filtered out: ${file:...} (path includes) and
${include:...}.
Behavior notes¶
- Requires
$HELIX_LICENSE. Verified at process start. - Unknown formats fail with
unsupported export format %q (supported: yaml, env, docker). - The Dockerfile output embeds
# Generated by Helix v<version>. The bundled YAML embeds a header naming the source file and a timestamp.
Examples¶
Generate a Dockerfile to stdout (default):
Generate a Dockerfile to disk:
Bundle every import into a single deployable YAML:
Extract the env template (sorted, deduplicated):
