Earthly requires Docker. Start Colima before running:
colima start
Check if running:
docker ps # Should not error
Doppler Access (For validation targets)
Required for +test-schema-validate and +test-schema-e2e:
doppler configure set token <token_from_1password>
doppler setup --project gapless-network-data --config prd
Earthly Installation
brew install earthly
Quick Commands
Generation only (no secrets)
cd /Users/terryli/eon/gapless-network-data
colima start # If not already running
earthly +test-schema-generate
Full E2E with validation (requires Doppler)
cd /Users/terryli/eon/gapless-network-data
colima start # If not already running
./scripts/earthly-with-doppler.sh +test-schema-e2e
All non-secret targets
cd /Users/terryli/eon/gapless-network-data
earthly +all
Artifacts
After running +test-schema-generate or +test-schema-e2e, check ./earthly-artifacts/:
| types/blocks.py
| Pydantic + TypedDict models
| types/__init__.py
| Package init
| ddl/ethereum_mainnet.sql
| ClickHouse DDL
| docs/ethereum_mainnet.md
| Markdown documentation
For E2E, artifacts are under e2e/types/, e2e/ddl/, e2e/docs/.

Troubleshooting
"could not determine buildkit address - is Docker or Podman running?"
Cause: Docker/Colima not running
Fix:
colima start
# Wait for "done" message, then retry
earthly +test-schema-generate
"unable to parse --secret-file argument"
Cause: Wrong flag name or malformed secrets file
Fix: The correct flag is --secret-file-path (NOT --secret-file). The wrapper script handles this, but if running manually:
# WRONG
earthly --secret-file=/path/to/secrets +target
# CORRECT
earthly --secret-file-path=/path/to/secrets +target
Also ensure secrets file has no quotes around values:
# WRONG format
CLICKHOUSE_HOST="host.cloud"
# CORRECT format
CLICKHOUSE_HOST=host.cloud
"OSError: Readme file does not exist: README.md"
Cause: hatchling build backend requires README.md in container
Fix: Ensure Earthfile copies README.md in deps target:
deps:
COPY pyproject.toml uv.lock README.md ./ # README.md required!
"missing secret" during validation
Cause: Doppler not configured or secrets not passed
Fix:
# Verify Doppler has the secrets
doppler secrets --project gapless-network-data --config prd | grep CLICKHOUSE
# Use the wrapper script (handles secret injection)
./scripts/earthly-with-doppler.sh +test-schema-validate
Cache Issues
Force rebuild without cache:
earthly --no-cache +test-schema-e2e
Implementation Details
Doppler Secret Injection
The wrapper script scripts/earthly-with-doppler.sh:
-
Downloads secrets from Doppler
-
Filters for
CLICKHOUSE_*variables -
Strips quotes (Doppler outputs
KEY="value", Earthly needsKEY=value) -
Passes via
--secret-file-pathflag -
Cleans up temp file on exit
Secrets Required
| CLICKHOUSE_HOST_READONLY
| ClickHouse Cloud host
| CLICKHOUSE_USER_READONLY
| Read-only user
| CLICKHOUSE_PASSWORD_READONLY
| Read-only password

Validation History
-
2025-12-03: Created and validated with full E2E run against ClickHouse Cloud
-
Lessons Learned:
--secret-file-path not --secret-file (Earthly v0.8.16)
-
Doppler
--format envoutputs quotes, must strip withsed 's/"//g' -
README.md must be copied for hatchling build backend
-
Colima must be started before Earthly runs
