# An OpenLDAP container
## Running with rkt
First be sure to clean any existing containers and turn SELinux to Permissive (this is due to a known issue in rkt).
sudo setenforce Permissive
sudo rkt gc --grace-period=0s
Run the OpenLDAP container at a predefined IP, this will set some initial values.
sudo rkt run --net=default:IP=172.16.28.25 quay.io/coreos/openldap:2.4.44
OpenLDAP will then be available on port 389. To work with the container's examples install the openldap client programs on your host.
sudo dnf install -y openldap-clients
`ldapadd` can be used to add new entries to the directory.
ldapadd \
-h 172.16.28.25 \
-D "cn=Manager,dc=example,dc=com" \
-w "secret" \
-f examples/example.ldif
The created entries can be searched with the `ldapsearch` command.
ldapsearch \
-h 172.16.28.25 \
-D "cn=Manager,dc=example,dc=com" \
-w "secret" \
-b "dc=example,dc=com" \
'(objectClass=*)'
## Customizing the created directory
The container uses environment variables defined in the `scripts/entrypoint.sh` bash file for initial configuration. Overriding these values will cause the
sudo rkt run \
--set-env=LDAP_DOMAIN="dc=dex,dc=coreos,dc=com" \
--set-env=LDAP_ROOT_CN="cn=admin" \
--set-env=LDAP_ROOT_PW="password" \
--net=default:IP=172.16.28.25 \
quay.io/coreos/openldap:2.4.44
## Development
The `Makefile` can be used to build the container using Docker. This will download OpenLDAP, compile it in a container, then add the entrypoint script.
make
General development looks like.
vim scripts/entrypoint.sh
make
sudo docker run -it --rm --entrypoint=/bin/sh quay.io/coreos/openldap:2.4.44
# poke around or run /entrypoint.sh manually
## TODO
* TLS support.
* Seed with initial data through mounted volume.
* Better `objectClass` schemas that match other LDAP deployments.
