- update docs to be more decriptive and cosistent with terminology
- Remove name and uid for the standby cluster
- Error out in case empty wal-path is provided for standby cluster
Instead of having a full-fledged standby cluster as in Patroni,
here we need lesser information, viz, S3 path, cluster name and uid.
It is more closer to clone now.
Override clone s3 bucket path
Add possibility to use a custom s3 bucket path for cloning a cluster
from an arbitrary bucket (e.g. from another k8s cluster). For that
a new config options is introduced `s3_wal_path`, that should point
to a location that spilo would understand.
* turns PostgresStatus type into a struct with field PostgresClusterStatus
* setStatus patch target is now /status subresource
* unmarshalling PostgresStatus takes care of previous status field convention
* new simple bool functions status.Running(), status.Creating()
Add possibility to mount a tmpfs volume to /dev/shm to avoid issues like
[this](https://github.com/docker-library/postgres/issues/416). To achieve that
two new options were introduced:
* `enableShmVolume` to PostgreSQL manifest, to specify whether or not mount
this volume per database cluster
* `enable_shm_volume` to operator configuration, to specify whether or not mount
per operator.
The first one, `enableShmVolume` takes precedence to allow us to be more flexible.
Client-go provides a https://github.com/kubernetes/code-generator package in order to provide the API to work with CRDs similar to the one available for built-in types, i.e. Pods, Statefulsets and so on.
Use this package to generate deepcopy methods (required for CRDs), instead of using an external deepcopy package; we also generate APIs used to manipulate both Postgres and OperatorConfiguration CRDs, as well as informers and listers for the Postgres CRD, instead of using generic informers and CRD REST API; by using generated code we can get rid of some custom and obscure CRD-related code and use a better API.
All generated code resides in /pkg/generated, with an exception of zz_deepcopy.go in apis/acid.zalan.do/v1
Rename postgres-operator-configuration CRD to OperatorConfiguration, since the former broke naming convention in the code-generator.
Moved Postgresql, PostgresqlList, OperatorConfiguration and OperatorConfigurationList and other types used by them into
Change the type of the Error field in the Postgresql crd to a string, so that client-go could generate a deepcopy for it.
Use generated code to set status of CRD objects as well. Right now this is done with patch, however, Kubernetes 1.11 introduces the /status subresources, allowing us to set the status with
the special updateStatus call in the future. For now, we keep the code that is compatible with earlier versions of Kubernetes.
Rename postgresql.go to database.go and status.go to logs_and_api.go to reflect the purpose of each of those files.
Update client-go dependencies.
Minor reformatting and renaming.
