+# Docker container of Greenplum DB based on Ubuntu 16
+
+This container raises the Greenplum database in "Single Instance" mode (master and two segments in one docker container). Use docker `-v` to mount host data directory to the container `/data` directory (as in example below).
+
+This dockerfile is using PPA for Ubuntu 16 — https://launchpad.net/~greenplum/+archive/ubuntu/db
+
+## Build and run
+```
+$ docker build -t local/gpdb .
+$ mkdir -p /tmp/gpdata/
+$ docker run -d -p 5432:5432 -h dwgpdb -v /tmp/gpdata:/data local/gpdb
+```
+The host name `dwgpdb` is strongly required to initializing the database properly with the same data from `/data` directory after restarting or rebuilding the container.
+
+## The first connect to GPDB from the host
+Review the docker logs to check that GPDB is installed and started up successfully:
+```
+$ docker ps -a
+$ docker logs --follow <GPDB_CONTAINDER_ID>
+```
+
+Connect:
+```
+# apt-get install postgresql-client-9.5
+$ psql -h 127.0.0.1 -p 5432 -U gpadmin
+Password: gppassword
+gpadmin=# select version();
+```
+
+## Using gp-utils in container
+File `greenplum_path.sh` added to `.bashrc` of `gpmaster` user so you can use gp-utils immediately in container:
+```
+$ docker ps
+$ docker exec -it <GPDB_CONTAINER_ID> bash
+# su gpadmin
+$ gpstate
+```
+
+## Stop database
+```
+$ docker ps
+$ docker stop <GPDB_CONTAINER_ID>
+```
