db2 on docker not showing sample database

I am trying to create a db2 instance and a sample database using docker. Below is my docker compose entry:

  db2:
    image: icr.io/db2_community/db2
    privileged: true
    restart: always
    environment:
      LICENSE: accept
      DB2INSTANCE: db2inst1
      DB2INST1_PASSWORD: password
      DBNAME: dbtest
      BLU: false
      TO_CREATE_SAMPLEDB: true
      IS_OSXFS: true
      REPODB: true
      HADR_ENABLED: false
      DOCKER_DEFAULT_PLATFORM: linux/amd64
    ports:
      - 50000:50000
    volumes:
      - db2:/database
    platform: linux/amd64

The container creates fine as far as I can see (including the sample database)

Now if I use DBeaver to connect I can't see the sample db (should be called testdb):

visible schemas

I don't think it is a missing connection setting (as I get the same view using PHPStorm too):

Connection settings

I would expect to see the TESTDB schema in the list of schemas. If I go into the container and run db2sampl to create the SAMPLE db I also can't see that. Is there a setting I need to change or is there something more fundamental wrong. I'm using a Macbook M2 Chip.

Solution

  • Quick Answer: Everything is fine, the database has been created, and you are connected to it.

    Details are as follows:

    docker-compose.yml

    version: '3.8'

services:
  db2:
    image: icr.io/db2_community/db2:latest    
    environment:
      - LICENSE=accept
      - DB2INSTANCE=db2inst1
      - DB2INST1_PASSWORD=password
      - DBNAME=dbtest
      - BLU=false
      - HADR_ENABLED=false
      - SAMPLEDB=true
      - REPODB=true
    ports:
      - "50000:50000"
    volumes:
      - db2:/database
    restart: always
    privileged: true

volumes:
  db2:
    driver: local

    Start DB2 Container

    docker-compose up -d

    View DB2 Logs

    Wait for a while... Probably 10 minutes or less...

    Run command and view log

    docker-compose logs -f db2

    If you see the following message, it is complete.

    ...
db2_1  |    Database Connection Information
db2_1  | 
db2_1  |  Database server        = DB2/LINUXX8664 12.1.1.0
db2_1  |  SQL authorization ID   = DB2INST1
db2_1  |  Local database alias   = DBTEST
db2_1  | 
db2_1  | DB20000I  The UPDATE DATABASE CONFIGURATION command completed successfully.
db2_1  | DB20000I  The UPDATE DATABASE CONFIGURATION command completed successfully.
...

    View Database dbtest (Use Default empty database)

    TOOL: dbeaver

    DB Connection

    URL: jdbc:db2://localhost:50000/dbtest

    enter image description here

    You are connected to the dbtest database, but it is an empty database by default.

    Create Table

    Menu SQL Editor -> New SQL script.

    enter image description here

    Enter the following SQL to create Table: STUDENTS.

    CREATE TABLE STUDENTS (
    id INT GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1) PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    age INT,
    grade VARCHAR(10),
    email VARCHAR(100),
    enrollment_date DATE
);

    execute sql script

    enter image description here

    Insert Data

    Enter the following SQL to insert data:

    INSERT INTO STUDENTS (name, age, grade, email, enrollment_date)
VALUES
('DB2 Alice', 20, 'A', 'db2.alice@example.com', '2025-03-07'),
('DB2 Bob', 22, 'B', 'db2.bob@example.com', '2025-02-10'),
('DB2 Charlie', 21, 'A', 'db2.charlie@example.com', '2025-03-02'),
('DB2 David', 23, 'C', 'db2.david@example.com', '2025-03-06'),
('DB2 Eva', 20, 'B', 'db2.eva@example.com', '2025-03-07');

    execute sql script

    enter image description here

    Now, You can see :

    enter image description here

    Select the table: STUDENTS
