1. start master node

  - `docker-compose up -d master-db`

2. create bootstrapping backup for slave-1

- `docker-compose up backup`

3. create bootstrapping backup for slave-2

- `docker-compose up backup2`

4. start slave nodes

- `docker-compose up -d slave-db`

- `docker-compose up -d slave-db2`

5. stop master node

- `docker-compose stop master-db`

6. uncomment synchronous_standby_names in master-config (and change it if you want to)

7. bring back master node

- `docker-compose start master-db`

8. verify that the replication works

- login into the master node

  1. `docker-compose exec master-db psql -U postgres`

- check replication stats

  1. `select * from pg_stat_replication`

- create some table and fill it with data:

  1. `create table example_data(content text not null);`

  2. `insert into example_data(content) values('first entry');`

- login into slave-db and verify that the data was replicated

  1. `docker-compose exec slave-db psql -U postgres`

  2. `select * from example_data;`
