## installation
[information about kubernetes deployment](https://stackoverflow.com/questions/25540711/docker-postgres-pgadmin-local-connection)
### RabbitMQ
```bash
sudo docker run -d --hostname my-rabbit --name some-rabbit \
-e RABBITMQ_DEFAULT_USER=guest \
-e RABBITMQ_DEFAULT_PASS=guest \
-p 15672:15672 -p 5671:5671 \
-p 5672:5672 -p 15671:15671 \
-p 25672:25672 rabbitmq:3-management
```
than connection string to mq is `amqp://guest:guest@localhost:5672`
### PLSQL
**If you didn't connect yet ensure that `$HOME/docker/volumes/postgres` is empty!**
Database is persited on `$HOME/docker/volumes/postgres` so if you run docker second time
do not remove this directory!
```bash
sudo docker run --rm --name pg-docker \
-e POSTGRES_PASSWORD=password \
-p 5432:5432 \
-v $HOME/docker/volumes/postgres:/var/lib/postgresql/data \
-d postgres:latest
```
If you require custom db and user:
```bash
sudo docker run --rm --name pg-docker \
-e POSTGRES_PASSWORD=password \
-e POSTGRES_USER=test \
-e POSTGRES_DB=test_db \
-p 5432:5432 \
-v $HOME/docker/volumes/postgres:/var/lib/postgresql/data \
-d postgres:latest
```
for troubleshooting run `telnet 127.0.0.1 22` from your machine
or `sudo docker exec -it bash` and check environment variables
by `env` command and login into database by `psql -h 127.0.0.1 -p 5432 -U test -d postgres --password`
`\l` shows list of available databases
When you create scheme you could export scheme this way...
```bash
sudo docker exec -it 5f31020172b8 pg_dump --schema-only --no-owner distributed -U test > create_the_tables.sql
```
### PGAdmin-4
```bash
sudo docker run -p 8085:80 \
--link pg-docker:pg-docker \
-e "[email protected]" \
-e "PGADMIN_DEFAULT_PASSWORD=password" \
-d dpage/pgadmin4
```
than run `localhost:8085` from your browser.
When create new server use `pg-docker` as Host and `5432` as port
`postgres` as database and user. For password use `password`
