// Keep for legacy reasons: remove after Omnibus has switched
FailoverEnabled bool `toml:"failover_enabled"`
MemoryQueueEnabled bool `toml:"memory_queue_enabled"`
GracefulStopTimeout config.Duration `toml:"graceful_stop_timeout"`
}
Config is a container for everything found in the TOML config file
func (Config) ConfigureLogger ¶
ConfigureLogger applies the settings from the configuration file to the logger, setting the log level and format.
func (Config) DefaultReplicationFactors ¶
DefaultReplicationFactors returns a map with the default replication factors of the virtual storages.
func (*Config) StorageNames ¶
StorageNames returns storage names by virtual storage.
func (*Config) VirtualStorageNames ¶
VirtualStorageNames returns names of all virtual storages configured.
type DB ¶
type DB struct {
Host string `toml:"host"`
Port int `toml:"port"`
User string `toml:"user"`
Password string `toml:"password"`
DBName string `toml:"dbname"`
SSLMode string `toml:"sslmode"`
SSLCert string `toml:"sslcert"`
SSLKey string `toml:"sslkey"`
SSLRootCert string `toml:"sslrootcert"`
SessionPooled DBConnection `toml:"session_pooled"`
// The following configuration keys are deprecated and
// will be removed. Use Host and Port attributes of
// SessionPooled instead.
HostNoProxy string `toml:"host_no_proxy"`
PortNoProxy int `toml:"port_no_proxy"`
}
DB holds database configuration data.
func (DB) ToPQString ¶
ToPQString returns a connection string that can be passed to github.com/lib/pq.
type DBConnection ¶
type DBConnection struct {
Host string `toml:"host"`
Port int `toml:"port"`
User string `toml:"user"`
Password string `toml:"password"`
DBName string `toml:"dbname"`
SSLMode string `toml:"sslmode"`
SSLCert string `toml:"sslcert"`
SSLKey string `toml:"sslkey"`
SSLRootCert string `toml:"sslrootcert"`
}
DBConnection holds Postgres client configuration data.
type ElectionStrategy ¶
type ElectionStrategy string
ElectionStrategy is a Praefect primary election strategy.
const ( // ElectionStrategyLocal configures a single node, in-memory election strategy. ElectionStrategyLocal ElectionStrategy = "local" // ElectionStrategySQL configures an SQL based strategy that elects a primary for a virtual storage. ElectionStrategySQL ElectionStrategy = "sql" // ElectionStrategyPerRepository configures an SQL based strategy that elects different primaries per repository. ElectionStrategyPerRepository ElectionStrategy = "per_repository" )
type Failover ¶
type Failover struct {
Enabled bool `toml:"enabled"`
// ElectionStrategy is the strategy to use for electing primaries nodes.
ElectionStrategy ElectionStrategy `toml:"election_strategy"`
ErrorThresholdWindow config.Duration `toml:"error_threshold_window"`
WriteErrorThresholdCount uint32 `toml:"write_error_threshold_count"`
ReadErrorThresholdCount uint32 `toml:"read_error_threshold_count"`
// BootstrapInterval allows set a time duration that would be used on startup to make initial health check.
// The default value is 1s.
BootstrapInterval config.Duration `toml:"bootstrap_interval"`
// MonitorInterval allows set a time duration that would be used after bootstrap is completed to execute health checks.
// The default value is 3s.
MonitorInterval config.Duration `toml:"monitor_interval"`
}
func (Failover) ErrorThresholdsConfigured ¶
ErrorThresholdsConfigured checks whether returns whether the errors thresholds are configured. If they are configured but in an invalid way, an error is returned.
type Node ¶
type Node struct {
Storage string `toml:"storage"`
Address string `toml:"address"`
Token string `toml:"token"`
}
Node describes an address that serves a storage
func (Node) MarshalJSON ¶
type Reconciliation ¶
type Reconciliation struct {
// SchedulingInterval the interval between each automatic reconciliation run. If set to 0,
// automatic reconciliation is disabled.
SchedulingInterval config.Duration `toml:"scheduling_interval"`
// HistogramBuckets configures the reconciliation scheduling duration histogram's buckets.
HistogramBuckets []float64 `toml:"histogram_buckets"`
}
Reconciliation contains reconciliation specific configuration options.
func DefaultReconciliationConfig ¶
func DefaultReconciliationConfig() Reconciliation
DefaultReconciliationConfig returns the default values for reconciliation configuration.
type Replication ¶
type Replication struct {
// BatchSize controls how many replication jobs to dequeue and lock
// in a single call to the database.
BatchSize uint `toml:"batch_size"`
}
Replication contains replication specific configuration options.
func DefaultReplicationConfig ¶
func DefaultReplicationConfig() Replication
DefaultReplicationConfig returns the default values for replication configuration.
type VirtualStorage ¶
type VirtualStorage struct {
Name string `toml:"name"`
Nodes []*Node `toml:"node"`
// DefaultReplicationFactor is the replication factor set for new repositories.
// A valid value is inclusive between 1 and the number of configured storages in the
// virtual storage. Setting the value to 0 or below causes Praefect to not store any
// host assignments, falling back to the behavior of replicating to every configured
// storage
DefaultReplicationFactor int `toml:"default_replication_factor"`
}
VirtualStorage represents a set of nodes for a storage
