---------------------------------------
Summary: Cannot change max heapsize in apache/activemq-classic
docker container
Key: AMQ-9471
URL: https://issues.apache.org/jira/browse/AMQ-9471
Project: ActiveMQ Classic
Issue Type: Bug
Components: Docker
Affects Versions: 5.18.3
Reporter: Richard Hierlmeier
I started the apache/activemq-classic with this docker-compose file:
{code:yaml}
version: "3.8"
services:
activemq:
image: apache/activemq-classic:5.18.3
container_name: activemq
expose:
- "61616"
- "5672"
- "61613"
- "1883"
- "61614"
- "8161"
- "1099"
ports:
- "8161:8161"
- "61616:61616"
- "5672:5672"
- "61613:61613"
- "1883:1883"
- "61614:61614"
- "1099:1099"
volumes:
- activemq_conf:/opt/apache-activemq/conf/
environment:
ACTIVEMQ_OPTS_MEMORY: "-Xms64M -Xmx2G"
command: activemq console
stdin_open: true
tty: true
volumes:
activemq_conf:
external: true
{code}
However the ACTIVEMQ_OPTS_MEMORY env variable is not considered. The max heap
size is still at the default value 1G:
{noformat}
$ docker-compose logs -f activemq
