2017-06-14Fix race conditions between containersJiri Stransky1-0/+1
In many occasions we had log directory initialization containers without `detach: false`, which didn't guarantee that they'll finish before the container depending on them will start using the log directory. This is now fixed by moving the initialization container one global step earlier, so that we can keep the concurrency when creating the log dirs. (Using `detach: false` makes paunch handle just one container at a time, and as such it can have negative performance impact.) For services which have their container(s) starting in step_1, initialization cannot be moved to an earlier step, so the solution here was to just add `detach: false`. As a minor related change, cinder DB sync container now mounts the log directory from host to put cinder-manage.log into the expected location. Change-Id: I1340de4f68dd32c2412d9385cf3a8ca202b48556
2017-05-15Add missing type for RoleParameters parameterMartin André1-0/+1
This was forgotten in I72376a803ec6b2ed93903cc0c95a6ffce718b6dc and broke containerized deployment. Change-Id: I599a87bf06efbfefd3067c77ed6ca866505900f9 Closes-Bug: #1690870
2017-05-15Add role specific information to the service templateSaravanan KR1-0/+9
When a service is enabled on multiple roles, the parameters for the service will be global. This change enables an option to provide role specific parameter to services and other templates. Two new parameters - RoleName and RoleParameters, are added to the service template. RoleName provides the role name of on which the current instance of the service is being applied on. RoleParameters provides the list of parameters which are configured specific to the role in the environment file, like below: parameters_default: # Default value for applied to all roles NovaReservedHostMemory: 2048 ComputeDpdkParameters: # Applied only to ComputeDpdk role NovaReservedHostMemory: 4096 In above sample, the cluster contains 2 roles - Compute, ComputeDpdk. The values of ComputeDpdkParameters will be passed on to the templates as RoleParameters while creating the stack for ComputeDpdk role. The parameter which supports role specific configuration, should find the parameter first in in the RoleParameters list, if not found, then the default (for all roles) should be used.

2017-05-05Mount hostpath logs on /var/logFlavio Percoco1-0/+11
Some containers are using the logs named volume for collecting logs written to `/var/log`. We should make this consistent for all the containers. This patch also cleans up some mounts that weren't needed for some services. For example, glance-api doesn't need `/run` to be mounted. Other changes: * Rework log volumes to hostpath mounts to omit slow COW writes. * Add kolla_config's permission and host_prep_tasks create and manage hostpath mounted log dirs permissions. * Rework data owning init containers to kolla_config permissions * When a step wants KOLLA_BOOTSTRAP or DB sync, use logs data owning init containers to set permissions for logs. This is required because kolla bootsrap and DB sync runs before the kolla config stage and there is yet permissions set for logs. * In order to address hybrid cases for host services vs containerized ones to access logs having different UIDs, persist containerized services' logs into separate directories (an upgrade impact) * Ensure host prep tasks to create /var/log/containers/ and /var/lib/ sub-directories for services * Fix missing /etc/httpd, /var/www config-data mounts for zaqar/ironic * Fix YAML indentation and drop strings quotation.

2017-05-02Move containers common volumes from yaql to list_concatJuan Antonio Osorio Robles1-7/+5
list_concat was introduced recently and is able to replace the yaql calls for concatenating lists. Change-Id: Id3a80a0e1e4c25b6d838898757c69ec99d0cd826
2017-04-18Introduce common resources for docker templatesJuan Antonio Osorio Robles1-3/+9
This enables common resources that the docker templates might need. The initial resource only is common volumes, and two volumes are introduced (localtime and hosts). Change-Id: Ic55af32803f9493a61f9b57aff849bfc6187d992
2017-03-10Remove docker_image sections (unused)Dan Prince1-5/+4
We don't use docker_image for anything. It is a remant of the pre-composable docker templates and we can now remove it. This patch removes references to the 'docker_image' section from docker/post.yaml and all of the docker/services* templates. Change-Id: I208c1ef1550ab39ab0ee47ab282f9b1937379810
2017-03-06Enable composable upgrades for docker service templatesSteven Hardy1-0/+4
This aligns the docker based services with the new composable upgrades architecture we landed for ocata, and does a first-pass adding upgrade_tasks for the services (these may change, atm we only disable the service on the host). To run the upgrade workflow you basically do two steps: openstack overcloud deploy --templates \ -e environments/major-upgrade-composable-steps-docker.yaml This will run the ansible upgrade steps we define via upgrade_tasks then run the normal docker PostDeploySteps to bring up the containers. For the puppet workflow there's then an operator driven step where compute nodes (and potentially storage nodes) are upgrades in batches and finally you do: openstack overcloud deploy --templates \ -e environments/major-upgrade-converge-docker.yaml In the puppet case this re-applies puppet to unpin the nova RPC API so I guess it'll restart the nova containers this affects but otherwise will be a no-op (we also disable the ansible steps at this point.

2017-03-01Put docker puppet config in puppet_config dictSteve Baker1-4/+7
This approach removes the need for the yaql zip to build the docker-puppet data by building the data in a puppet_config dict. This allows a future change to make docker-puppet.py only accept dict data. Currently the step_config is left where it is and referenced inside puppet_config, but feedback is welcome whether this is necessary or desirable. Change-Id: I4a4d7a6fd2735cb841174af305dbb62e0b3d3e8c
