Ands (Advanced aNalysis and Data Services)
Ansible groups
==============
- OpenShift
nodes [enforced] All OpenShift Nodes
storage_nodes All OpenShift Nodes with attached storage
masters [enforced] All OpenShift Nodes with attached storage and acting as masters
Additional building blocks:
simple_nodes OpenShift Node (without Storage)
simple_storage_nodes OpenShift Node with Storage atached, but not acting as Master
- oVirt
? ovirt_servers All oVirt servers
? ovirt_masters All oVirt masters
- General
ands_servers All server hardware running in the server rooms
ands_storage_servers All servers with storage attached (OpenShift storage, oVirt storage, PDV storage)
ands_cuda_servers All servers with NVIDIA hardware
ands_opencl_servers All servers expected to run OpenCL SDK
ands_desktops Destkop computers outside of the server room
ands Everything
Ansible roles
=============
- Preparation of Vagrant nodes
ands_vagrant_vm vagrant Configures Vagrantfile and starts virtual machines if necessary
- Ands-specific
ands_facts ands Detect current Ands configuration
ands_storage ands_storage_servers Detects large storage device and configures LVM, sets aside space for Heketi if ands_heketi_* is set
- General (abstract roles)
common ands Standard repositories & software
keepalived masters Keepalived Service
openvpn nodes Configures required tunnels (contains templates for all planned tunnels)
docker nodes Installs docker and configures LVM-based docker storage backend
glusterfs servers Installs glusterfs, provisions requested volumes, and mounts them
- OpenShift
openshift_resource include Populates OpenShift resources (should be executed on master nodes)
ands_openshift nodes Configures /etc/hosts (to be independent of DNS), user accounts, GlusterFS endpoints in all projects, Heketi service if needed
ands_kaas masters For all projects configure Gluster volumes, populates OpenShift resources and configuration user configuration
- Katrin-specific
kaas
Ansible parameters (global)
==================
We are listing here only variables which have the global scope, i.e. affect multiple roles. The role parameters are documented
within the role itself. General (non ands_*) roles should not rely on ands_* variables directly (except in 'defaults').
=> Instead the playbooks are used to set role-specific parameters based on ands_* variables.
- Domains
ands_openshift_subdomain group_vars The default subdomain of the OpenShift cluster (kaas.kit.edu)
ands_cluster_domain group_vars The default domain name of all cluster servers (.ipe.kit.edu)
- High Availability
ands_openshift_lb group_vars The FQDN of load-balancer of the OpenShift cluster (katrin.kit.edu)
ands_ipfailover_interface group_vars Interface to run IPFailover service
ands_ipfailover_vips group_vars Virtual IPs to maintain by IPFailover service
- Networks
ands_storage_network group_vars CIDR of storage network
ands_openshift_network group_vars CIDR of OpenShift network (normally, we use storage network)
ands_openshift_public_network group_vars CIDR of OpenShift public network (normally, we use infrastructure network)
ands_openshift_ingress_network group_vars CIDR of OpenShift ingress network
- Host names / IPs
ands_host_id inventory ID is equivalent to the IP in the infrastructure network
ands_storage_hostname computed IP or hostname of the host in the Infiniband storage network
ands_hpc_hostname computed IP or hostname of the host in the Infiniband HPC network
- Storage
ands_data_device ands_storage The raid device where Ands LVM will be populated. Normally will be autodetected based on size.
ands_data_vg ands_storage The LVM VG on the main storage device
ands_data_path ands_storage The path where the large storage is mounted
ands_data_volume_size group_vars If not specified, all disks space will be imideately used. Oherwise, it is possible to keep it for other uses and grow as needed.
ands_heketi_volume_size group_vars If specified, some space will set aside on LVM some space for Heketi volume
ands_storage_domains ands_storage List of GlusterFS volumens and mount points (configured in ands_facts and may add additional heketi domain in ands_storage)
- Docker specific
docker_storage_device ands_storage Storage device to create Docker LVM on (if not existing yet)
docker_storage_vg ands_storage LVM VG for Docker volumes (autodetected if not specified)
- GlusterFS specific
glusterfs_version group_vars
glusterfs_transport group_vars
- OpenShift specific
ands_openshift_labels setup/configs Labels to assign to the nodes
ands_openshift_projects setup/configs List of projects to configure (with GlusterFS endpoints, etc.)
ands_openshift_users setup/configs Optional list of user names with contacts
ands_openshift_roles setup/configs User-permissions. Configures list of admins, project users, etc.
ands_secrets setup/configs Passwords, etc.
ands_paths setup/configs Default mount point paths
ands_storage_domains setup/configs List of GlusterFS volumes along with hosting servers
ands_openshift_volumes setup/configs List of OpenShift volumes linked to GlusterFS volumes and paths. Used to generate PV/PVC. Can be restricted per project.
ands_openshift_files setup/configs List of directories/files on the GlusterFS we want to create, ensure permissions/owners.
kaas_glusterfs_endpoints <hard-corded> Specifies the name of GlusterFS endpoint, should be configured by the ands_openshift service (but currently hardcorded)
- Project specific
volumes project Overrides list of PV/PVC to populate in the project
files project Additional files to ensure are existing and have correct permissions
file_owner project Default user owning files
file_group project Default group owning files
pods project Configuration of the expected pods
oc project If necessary may give detailed instructions in which prioritu resources should be populated
- KATRIN specific
katrin_node group_vars FQDN of KaaS router (katrin.kit.edu, but now katrin.ipe.kit.edu or something)
katrin_openvpn_network group_vars OpenVPN network encompassing all subnets to Katrin control network
katrin_openvpn_subnet_bits group_vars Subnet size
katrin_openvpn_subnet_offset group_vars Offset of a first subnet (according to the specified size)
