To build the containers
cd hazdev-geoserve-ws
docker build -t usgs/hazdev-geoserve-db:latest -f Dockerfile-db .
docker build -t usgs/hazdev-geoserve-ws:latest -f Dockerfile-ws .
You may optionally specify a few --build-arg switches to customize the build.
BUILD_IMAGEThe name of the Docker image to use in the first stage of creating the image.FROM_IMAGEThe name of the Docker image to use in the second stage of creating the image.
To run the containers
The following examples demonstrate environment variables used by the containers:
# start database container
# data load may take a while on first run
docker run --rm --name=geoservedb -d \
-e POSTGRES_PASSWORD=changethis \
-e PGDATA=/var/lib/postgresql/data/pgdata \
-v $(pwd)/data/pgdata:/var/lib/postgresqsl/data/pgdata \
-e 'DB_ADMIN_DSN=pgsql:dbname=earthquake' \
-e DB_ADMIN_USER=postgres \
-e DB_ADMIN_PASSWORD=changethis \
-e DB_LOAD_TYPE=incremental \
-e DB_NAME=earthquake \
-e DB_SCHEMA=geoserve \
-e DB_USER=web \
-e DB_PASS=alsochangethis \
usgs/hazdev-geoserve-db:latest
# start webservice container
docker run --rm --name=geoserve -d \
-p 8080:80 \
--link geoservedb:geoservedb \
-e 'DB_DSN=pgsql:host=geoservedb;port=5432;dbname=earthquake' \
-e DB_USER=web \
-e DB_PASS=alsochangethis \
-e DB_SCHEMA=geoserve \
usgs/hazdev-geoserve-ws:latest
