* Change error computation on JSON Unmarshall The [Unmarshall function][1] on the encoding/JSON default library returns different errors for different go versions. On Go 1.12, the version used currently on the CI system it returns `json: cannot unmarshal number into Go struct field PostgresSpec.teamId of type string`. On Go 1.13.5 it returns `json: cannot unmarshal number into Go struct field PostgresSpec.spec.teamId of type string`. The new version includes more details of the whole structure being unmarshelled. This commit introduces the same error but one level deeper on the JSON structure. It creates consistency across different Go versions. [1]: https://godoc.org/encoding/json#Unmarshal * Create subtests on table test scenarios The Run method of T allows defining subtests creating hierarchical tests. It provides better visibility of tests in case of failure. More details on https://golang.org/pkg/testing/. This commit converts each test scenario on pkg/apis/acid.zalan.do/v1/util_test.go to subtests, providing a better visibility and the debugging environment when working with tests. The following code snippet shows an error during test execution with subtests: ``` --- FAIL: TestUnmarshalMaintenanceWindow (0.00s) --- FAIL: TestUnmarshalMaintenanceWindow/expect_error_as_'From'_is_later_than_'To' (0.00s) ``` It included a `about` field on test scenarios describing the test purpose and/or it expected output. When a description was provided with comments it was moved to the about field.
Postgres Operator
The Postgres Operator enables highly-available PostgreSQL clusters on Kubernetes (K8s) powered by Patroni. It is configured only through manifests to ease integration into automated CI/CD pipelines with no access to Kubernetes directly.
Operator features
- Rolling updates on Postgres cluster changes
- Volume resize without Pod restarts
- Cloning Postgres clusters
- Logical Backups to S3 Bucket
- Standby cluster from S3 WAL archive
- Configurable for non-cloud environments
- UI to create and edit Postgres cluster manifests
PostgreSQL features
- Supports PostgreSQL 9.6+
- Streaming replication cluster via Patroni
- Point-In-Time-Recovery with pg_basebackup / WAL-E via Spilo
- Preload libraries: bg_mon, pg_stat_statements, pgextwlist, pg_auth_mon
- Incl. popular Postgres extensions such as decoderbufs, hypopg, pg_cron, pg_partman, pg_stat_kcache, pgq, plpgsql_check, postgis, set_user and timescaledb
The Postgres Operator has been developed at Zalando and is being used in production for over two years.
