How to Build
# continuous integration and deployment
docker stop ldapds;docker rm ldapds;\
docker build --rm -t 'chorke/ldap:16.04' ./;\
docker rmi $(docker images -qa -f 'dangling=true');\
docker run --name='ldapds' -d -p 9030:80 -p 389:389 chorke/ldap:16.04;\
docker exec -it ldapds bash
How to Create
# for first time to create container from docker image and shell access
docker run --name='ldapds' -d -p 9030:80 -p 389:389 chorke/ldap:16.04
docker exec -it ldapds bash
/root/.docker/init.sh
How to Control
# access, start, stop & restart
docker exec -it ldapds bash
docker restart ldapds
docker start ldapds
docker stop ldapds
Good to Know
# filter and remove docker images, containers
docker rm $(docker ps --all -q -f status=dead)
docker rmi $(docker images -qa -f 'dangling=true')
docker rm ldapds && docker rmi chorke/ldap:16.04
# docker container debug, checking history & service
docker run --name='ldapds' -it chorke/ldap:16.04 bash
docker history chorke/ldap:16.04
docker exec -it ldapds bash
service --status-all
