Short Description
Mamute is a Q&A Engine - This image is based on java:8-jdk and uses Mamute 1.5.0
Full Description


The image is based on the java:8-jdk base image, fetches Mamute version 1.5.0, extracts and places a startup script file that does all the magic.

Purpose of container

Provide an easy way to deploy Mamute in production with very easy configuration options.
Mamute stores it's data in a MySQL.


MySQL version 5.7.4 works well with Mamute 1.5.0 any version above 5.7.4 will fail and break and cause the polar ice caps to melt

Eager to try it?

Start a MySQL container:

docker run -d \
    --name mysql-mamute \
    -e MYSQL_ROOT_PASSWORD=secretpassword \
    -e MYSQL_DATABASE=mamute \
    -e MYSQL_USER=mamute \
    -e MYSQL_PASSWORD=mamute \

Start a Mamute container:

docker run -d \
    --name mamute \
    --link mysql-mamute:mysql \
    -e MAMUTE_PORT=8080 \
    -p 8080:8080 \

This is enough to test Mamute on localhost on port 8080. Navigate to http://localhost:8080.

After about a year (with version 1.4.0), the application stops working with this message in logs:

[Note] Your password has expired. To log in you must change it using a client that supports expired passwords.

The solution is :

docker exec -it mamute_db_1 bash
mysql -u root -p --connect-expired-password (enter secretpassword)
SET PASSWORD = PASSWORD('secretpassword');
docker exec -it mamute_db_1 bash
mysql -u mamute -p --connect-expired-password (enter mamute)

Example of docker-compose.yml :

version: '2'
    image: mysql:5.7.4
    restart: always
      - MYSQL_ROOT_PASSWORD=secretpassword
      - MYSQL_DATABASE=mamute
      - MYSQL_USER=mamute
      - MYSQL_PASSWORD=mamute
      - "3306:3306"
      - /path/of/docker/containers/mamute/data:/var/lib/mysql

      - db
    image: jbasila/mamute:1.4.0
    restart: always
      - MAMUTE_PORT=8080
      - "8080:8080"
     - db:mysql
