…nts (#11) Fixes #9 The zallet container was failing with "Permission denied (os error 13)" due to overlapping Docker mounts. Config files were bind-mounted inside the data volume at /var/lib/zallet/, causing Docker to create them with root ownership while the container runs as UID 65532. This commit resolves the issue by: - Mounting config files to /etc/zallet/ instead of /var/lib/zallet/ - Adding --config flag to zallet command to specify config location - Using absolute path for encryption_identity in zallet.toml The fix works on both mainnet and testnet as it addresses Docker configuration, not network-specific settings. Changes: - docker-compose.yml: Updated zallet command and volume mount paths - config/zallet.toml: Changed encryption_identity to absolute path Tested on testnet - zallet now starts successfully without permission errors.
* feat(docker): update to latest zaino and official zallet image Update submodules and Docker configuration: - Zaino: use GHCR image sha-417b679 (built from zingolabs/zaino:dev) - Zallet: v0.1.0-alpha.3 (electriccoinco/zallet official image) - Zebra: v3.1.0 (unchanged) Add custom entrypoint for Zaino to resolve Docker DNS hostnames to IP addresses, required because ValidatorConfig uses SocketAddr type which only accepts IP:port format, not hostname:port. NOTE: The entrypoint workaround can be removed once zaino PR #784 is merged and a new image is built: zingolabs/zaino#784 New files: - config/zaino/docker-entrypoint.sh (temporary workaround) - config/zaino/zindexer.toml * refactor(docker): remove zaino DNS workaround and update submodules Remove the docker-entrypoint.sh workaround for Zaino hostname resolution now that upstream PR #784 adds native support for hostname:port format. Changes: - Remove config/zaino/docker-entrypoint.sh (no longer needed) - Simplify config/zaino/zindexer.toml to minimal config-rs requirement - Update docker-compose.yml to use native hostname resolution - Remove env_file from zaino service (conflicts with config-rs) - Update submodules to latest versions: - zaino: 49e5241d (config-rs migration + hostname support) - zebra: e04845f3e - zcashd: cfcfcd93b (v6.11.0) * chore(docker): update zaino image to sha-1871eba
…AlertManager Add optional observability stack enabled via Docker Compose profiles: - Prometheus (v3.2.0) for metrics collection - Grafana (11.5.1) with 14 pre-built Zebra dashboards - Jaeger (2.1.0) for distributed tracing (future Zebra releases) - AlertManager (v0.28.1) for alert routing Usage: docker compose --profile monitoring up -d Also updates: - Zebra image from 3.1.0 to 4.0.0 - README to reflect all services now use pre-built remote images - .env with monitoring configuration options
