Environment variables
To configure Weaviate in a Docker or a Kubernetes deployment, set these environment variables
Boolean environment variables
For Boolean environment variables, "on", "enabled", "1", and "true" are interpreted as true.
All other values are interpreted as false.
General
| Variable | Description | Type | Example Value |
|---|---|---|---|
ASYNC_INDEXING | (Experimental as of v1.22.) If set, Weaviate creates vector indexes asynchronously to the object creation process. This can be useful for importing large amounts of data. (default: false) | boolean | false |
AUTOSCHEMA_ENABLED | Whether to infer the schema where necessary with the autoschema (default: true) | boolean | true |
DEFAULT_VECTORIZER_MODULE | Default vectorizer module - will be overridden by any class-level value defined in the schema | string | text2vec-contextionary |
DISABLE_LAZY_LOAD_SHARDS | New in v1.23. When false, enable lazy shard loading to improve mean time to recovery in multi-tenant deployments. | string | false |
DISABLE_TELEMETRY | Disable telemetry data collection | boolean | false |
DISK_USE_READONLY_PERCENTAGE | If disk usage is higher than the given percentage all shards on the affected node will be marked as READONLY, meaning all future write requests will fail. See Disk Pressure Warnings and Limits for details. | string - number | 90 |
DISK_USE_WARNING_PERCENTAGE | If disk usage is higher than the given percentage a warning will be logged by all shards on the affected node's disk. See Disk Pressure Warnings and Limits for details. | string - number | 80 |
DISABLE_GO_PROFILING | If true, disables Go profiling. Default: false. | boolean | false |
ENABLE_API_BASED_MODULES | Enable all API-based modules. (Experimental as of v1.26.0) | boolean | true |
ENABLE_MODULES | Specify Weaviate modules to enable | string - comma separated names | text2vec-openai,generative-openai |
ENABLE_TOKENIZER_GSE | Enable the GSE tokenizer for use | boolean | true |
ENABLE_TOKENIZER_KAGOME_KR | Enable the Kagome tokenizer for Korean for use (Experimental as of v1.25.7) | boolean | true |
GODEBUG | Controls debugging variables within the runtime. See official Go docs. | string - comma-separated list of name=val pairs | gctrace=1 |
GOMAXPROCS | Set the maximum number of threads that can be executing simultaneously. If this value is set, it be respected by LIMIT_RESOURCES. | string - number | NUMBER_OF_CPU_CORES |
GOMEMLIMIT | Set the memory limit for the Go runtime. This should match your available memory, such as 10-20% of your total memory for Weaviate. The Go runtime tries to make sure that long-lived and temporary memory allocations do not exceed this value by making the garbage collector more aggressive as the memory usage approaches the limit. Learn more about GOMEMLIMIT. | string - memory limit in SI units | 4096MiB |
LIMIT_RESOURCES | If true, Weaviate will automatically attempt to auto-detect and limit the amount of resources (memory & threads) it uses to (0.8 * total memory) and (number of cores-1). It will override any GOMEMLIMIT values, however it will respect GOMAXPROCS values. | boolean | false |
LOG_FORMAT | Set the Weaviate logging format Default: Outputs log data to json. e.g.: {"action":"startup","level":"debug","msg":"finished initializing modules","time":"2023-04-12T05:07:43Z"} text: Outputs log data to a string. e.g. time="2023-04-12T04:54:23Z" level=debug msg="finished initializing modules" action=startup | string | |
