PostgreSQL demo
This demo shows how to run midPoint container with PstgreSQL repository implementation.
The image can be found in the Evolveum/midpoint-docker GitHub project.
Starting
After docker-compose up
command successfully finishes you should see something like this on the console:
postgresql_midpoint_server_1 | 2019-02-22 15:07:50,222 [] [main] INFO (org.springframework.boot.web.embedded.tomcat.TomcatWebServer): Tomcat started on port(s): 8080 (http) with context path '/midpoint'
postgresql_midpoint_server_1 | 2019-02-22 15:07:50,230 [] [main] INFO (com.evolveum.midpoint.web.boot.MidPointSpringApplication): Started MidPointSpringApplication in 74.425 seconds (JVM running for 77.109)
Now you can log into midPoint using http://localhost:8080/midpoint URL, with an user of administrator
and a password of 5ecr3t
.
You can safely ignore console messages like this:
postgresql_midpoint_data_1 | ERROR: could not serialize access due to read/write dependencies among transactions
postgresql_midpoint_data_1 | DETAIL: Reason code: Canceled on identification as a pivot, during write.
postgresql_midpoint_data_1 | HINT: The transaction might succeed if retried.
This is a part of standard midPoint conflict resolution process. The mentioned transactions are really retried and they succeed eventually.
Containers
The demo/postgresql
composition contains the following containers:
Container name | Description |
