This Docker container is crafted on CentOS 8, integrating OpenLDAP and Kerberos 5. It's meticulously configured to enable access to systemd, facilitating the management of services like slapd through systemctl commands within the container's environment.
Leveraging the robustness of CentOS as its foundation, this project is aimed at simplifying the deployment and management of LDAP services within a containerized ecosystem. The inclusion of systemd within the Docker container streamlines service management, making it more efficient to administer slapd operations.
Whether you're building locally or pulling directly from Docker Hub, here's how you get started:
- Build Locally:
docker build -t centos-openldap-krb5 --platform=linux/amd64 . - Pull from Docker Hub:
docker pull adiadev/centos-openldap-krb5:latest
To run the container with systemd access:
docker run -d -h example.com --platform=linux/amd64 --privileged=true centos-openldap-krb5
Here's what each parameter does:
-d: Detached mode, allowing the container to run in the background.-h example.com: Sets the container's hostname (feel free to customize this).--platform=linux/amd64: Specifies the container's architecture (adjust as needed, I had to specify this for my Mac with an Apple Silicon chip).--privileged=true: Enables privileged access for interacting with systemd.
For managing the OpenLDAP service within your container:
docker exec -it <container_id> systemctl enable slapd
docker exec -it <container_id> systemctl start slapd
docker exec -it <container_id> systemctl status slapd
Alternatively, for direct command line access within the container:
docker exec -it <container_id> /bin/bash
# Then run the following commands within the container's shell
systemctl enable slapd
systemctl start slapd
systemctl status slapd
This container setup is intended for development and testing environments, offering a sandbox for LDAP and Kerberos experiments and learning.
