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 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)
