ScadaBridge/docker-env2

ScadaBridge Env2 Docker Infrastructure

A second Docker deployment of a minimal ScadaBridge cluster topology, designed to run concurrently with the primary docker/ stack so the Transport (#24) feature can be exercised end-to-end across two real environments.

See docs/plans/2026-05-24-second-environment-design.md for the design rationale.

Port Allocation

Env2 host ports are the primary's ports + 100. Both stacks can run simultaneously.

Node	Container Name	Host Web	Host Akka	Host gRPC	Internal
Traefik LB	scadabridge-env2-traefik	9100	—	—	80 (proxy), 8080 (dashboard host:8181)
Central A	scadabridge-env2-central-a	9101	9111	9113	5000 (web), 8081 (Akka), 8083 (gRPC)
Central B	scadabridge-env2-central-b	9102	9112	9114	5000 (web), 8081 (Akka), 8083 (gRPC)
Site-X A	scadabridge-env2-site-x-a	—	9121	9123	8082 (Akka), 8083 (gRPC)
Site-X B	scadabridge-env2-site-x-b	—	9122	9124	8082 (Akka), 8083 (gRPC)

Shared Infrastructure

Env2 attaches to the existing scadabridge-net Docker bridge network and reuses these primary infra containers:

Service	Container	What env2 uses it for
MS SQL	scadabridge-mssql	Env2-specific databases ScadaBridgeConfig2 / ScadaBridgeMachineData2
SMTP	scadabridge-smtp	Notification capture in Mailpit (env2 emails distinguishable by FromAddress)
OPC UA	scadabridge-opcua	Simulated tags for site-x data connections
REST API	scadabridge-restapi	External REST API testing

LDAP is not one of the reused infra/ containers (that stack's ldap service is retired/commented out). Env2's central nodes bind to the same local redundant GLAuth pair as docker/ — zb-ldap-primary on host.docker.internal:3893 with zb-ldap-backup on host.docker.internal:3894 as FallbackServers (source of truth: scadaproj/infra/glauth-redundant); same test users, same bind credentials as the primary stack.

Commands

First-Time Setup

# 1. Make sure primary infra is up (creates scadabridge-net, scadabridge-mssql, etc.)
cd infra && docker compose up -d && cd ..

# 2. Build image + create env2 databases + deploy env2 containers
bash docker-env2/deploy.sh

# 3. Seed env2's single test site (first-time only)
bash docker-env2/seed-sites.sh

The seed also creates a native alarm source demo: a MxAlarmDemo template with a GalaxyAlarms native alarm source bound to the shared MxGateway connection, plus a deployed MxAlarmDemo-1 instance on site-x. This exercises the read-only native alarm mirror end-to-end — mirrored alarms appear live in the Central UI Debug View with severity and condition badges. Verify the binding with:

scadabridge --url http://localhost:9100 template native-alarm-source list --template-id <id>

After Code Changes

bash docker-env2/deploy.sh

The Docker build is shared with the primary stack — if you've just run docker/deploy.sh, the env2 build hits a fully cached image.

Running Both Stacks Concurrently

bash docker/deploy.sh         # primary
bash docker-env2/deploy.sh    # env2

Both UIs are now reachable:

• Primary: http://localhost:9000
• Env2: http://localhost:9100

Teardown

bash docker-env2/teardown.sh

Containers stop; node data lives in named Docker volumes (scadabridge-env2-*-data) and logs in node directories, both left in place. To also remove the persistent data:

# Destructive: deletes all env2 SQLite data (site config cache, S&F buffers, LocalDb).
docker volume rm $(docker volume ls -q --filter name=scadabridge-env2-)
rm -rf docker-env2/*/logs

To also drop the env2 databases:

docker exec scadabridge-mssql /opt/mssql-tools18/bin/sqlcmd \
    -S localhost -U sa -P 'ScadaBridge_Dev1#' -C \
    -Q "DROP DATABASE ScadaBridgeConfig2; DROP DATABASE ScadaBridgeMachineData2;"

CLI Access

dotnet run --project src/ZB.MOM.WW.ScadaBridge.CLI -- \
    --url http://localhost:9100 \
    --username multi-role --password password \
    template list

View Logs

docker compose -f docker-env2/docker-compose.yml logs -f
docker logs -f scadabridge-env2-central-a

Test Users

Same as primary (env2 shares the local redundant GLAuth pair, scadaproj/infra/glauth-redundant). See "Shared Infrastructure" above and primary docker/README.md.

Transport Testing Workflow

See docs/plans/2026-05-24-second-environment-verification.md for the manual golden-path checklist.

What's Different from Primary

• Single site (site-x) instead of three (site-a/b/c).
• Host port range 91XX vs primary 90XX.
• Container names prefixed scadabridge-env2-.
• Databases ScadaBridgeConfig2 / ScadaBridgeMachineData2 on the shared scadabridge-mssql.
• Transport.SourceEnvironment = "docker-cluster-env2" (stamped into exported bundle manifests).
• Distinct Security.JwtSigningKey (sessions cannot cross envs).
