qdrant支持环境变量配置修改、config文件配置修改

1、config文件样本

log_level: INFO

storage:
  # Where to store all the data
  storage_path: ./storage

  # Where to store snapshots
  snapshots_path: ./snapshots

  snapshots_config:
    # "local" or "s3" - where to store snapshots
    snapshots_storage: local
    # s3_config:
    #   bucket: ""

    #   secret_key: ""

  # Where to store temporary files
  # If null, temporary snapshot are stored in: storage/snapshots_temp/
  temp_path: null

  # If true - point's payload will not be stored in memory.
  # It will be read from the disk every time it is requested.
  # This setting saves RAM by (slightly) increasing the response time.
  # Note: those payload values that are involved in filtering and are indexed - remain in RAM.
  on_disk_payload: true

  # Maximum number of concurrent updates to shard replicas
  # If `null` - maximum concurrency is used.
  update_concurrency: null

  # Write-ahead-log related configuration
  wal:
    # Size of a single WAL segment
    wal_capacity_mb: 32

    # Number of WAL segments to create ahead of actual data requirement
    wal_segments_ahead: 0

  # Normal node - receives all updates and answers all queries
  node_type: "Normal"

  # Listener node - receives all updates, but does not answer search/read queries
  # Useful for setting up a dedicated backup node
  # node_type: "Listener"

  performance:
    # Number of parallel threads used for search operations. If 0 - auto selection.
    max_search_threads: 0

    # Max number of threads (jobs) for running optimizations across all collections, each thread runs one job.
    # If 0 - have no limit and choose dynamically to saturate CPU.
    # Note: each optimization job will also use `max_indexing_threads` threads by itself for index building.
    max_optimization_threads: 0

    # CPU budget, how many CPUs (threads) to allocate for an optimization job.
    # If 0 - auto selection, keep 1 or more CPUs unallocated depending on CPU size
    # If negative - subtract this number of CPUs from the available CPUs.
    # If positive - use this exact number of CPUs.
    optimizer_cpu_budget: 0

    # Prevent DDoS of too many concurrent updates in distributed mode.
    # One external update usually triggers multiple internal updates, which breaks internal
    # timings. For example, the health check timing and consensus timing.
    # If null - auto selection.
    update_rate_limit: null

    # Limit for number of incoming automatic shard transfers per collection on this node, does not affect user-requested transfers.
    # The same value should be used on all nodes in a cluster.
    # Default is to allow 1 transfer.
    # If null - allow unlimited transfers.
    #incoming_shard_transfers_limit: 1

    # Limit for number of outgoing automatic shard transfers per collection on this node, does not affect user-requested transfers.
    # The same value should be used on all nodes in a cluster.

  optimizers:
    # The minimal fraction of deleted vectors in a segment, required to perform segment optimization
    deleted_threshold: 0.2

    # The minimal number of vectors in a segment, required to perform segment optimization
    vacuum_min_vector_number: 1000

    # Target amount of segments optimizer will try to keep.
    # Real amount of segments may vary depending on multiple parameters:
    #  - Amount of stored points
    #  - Current write RPS
    #
    # It is recommended to select default number of segments as a factor of the number of search threads,
    # so that each segment would be handled evenly by one of the threads.
    # If `default_segment_number = 0`, will be automatically selected by the number of available CPUs
    default_segment_number: 0

    # Do not create segments larger this size (in KiloBytes).
    # Large segments might require disproportionately long indexation times,
    # therefore it makes sense to limit the size of segments.
    #
    # If indexation speed have more priority for your - make this parameter lower.
    # If search speed is more important - make this parameter higher.
    # Note: 1Kb = 1 vector of size 256
    # If not set, will be automatically selected considering the number of available CPUs.
    max_segment_size_kb: null

    # Maximum size (in KiloBytes) of vectors to store in-memory per segment.
    # Segments larger than this threshold will be stored as read-only memmaped file.

    indexing_threshold_kb: 20000

    # Interval between forced flushes.
    flush_interval_sec: 5

    # Max number of threads (jobs) for running optimizations per shard.
    # Note: each optimization job will also use `max_indexing_threads` threads by itself for index building.
    # If null - have no limit and choose dynamically to saturate CPU.
    # If 0 - no optimization threads, optimizations will be disabled.
    max_optimization_threads: null

  # This section has the same options as 'optimizers' above. All values specified here will overwrite the collections
  # optimizers configs regardless of the config above and the options specified at collection creation.
  #optimizers_overwrite:
  #  deleted_threshold: 0.2
  #  vacuum_min_vector_number: 1000
  #  default_segment_number: 0

  #  max_optimization_threads: null

  # Default parameters of HNSW Index. Could be overridden for each collection or named vector individually
  hnsw_index:
    # Number of edges per node in the index graph. Larger the value - more accurate the search, more space required.
    m: 16

    # Number of neighbours to consider during the index building. Larger the value - more accurate the search, more time required to build index.
    ef_construct: 100

    # Minimal size (in KiloBytes) of vectors for additional payload-based indexing.
    # If payload chunk is smaller than `full_scan_threshold_kb` additional indexing won't be used -
    # in this case full-scan search should be preferred by query planner and additional indexing is not required.
    # Note: 1Kb = 1 vector of size 256
    full_scan_threshold_kb: 10000

    # Number of parallel threads used for background index building.
    # If 0 - automatically select.
    # Best to keep between 8 and 16 to prevent likelihood of building broken/inefficient HNSW graphs.
    # On small CPUs, less threads are used.
    max_indexing_threads: 0

    # Store HNSW index on disk. If set to false, index will be stored in RAM. Default: false
    on_disk: false

    # Custom M param for hnsw graph built for payload index. If not set, default M will be used.
    payload_m: null

  # Default shard transfer method to use if none is defined.

  host: 0.0.0.0

  # HTTP(S) port to bind the service on
  http_port: 6333

  # gRPC port to bind the service on.
  # If `null` - gRPC is disabled. Default: null
  # Comment to disable gRPC:
  grpc_port: 6334

  # Enable CORS headers in REST API.
  # If enabled, browsers would be allowed to query REST endpoints regardless of query origin.
  # More info: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
  # Default: true
  enable_cors: true

  # Enable HTTPS for the REST and gRPC API
  enable_tls: false

  # Check user HTTPS client certificate against CA file specified in tls config
  verify_https_client_certificate: false

  # Set an api-key.
  # If set, all requests must include a header with the api-key.
  # example header: `api-key: <API-KEY>`
  #
  # If you enable this you should also enable TLS.
  # (Either above or via an external service like nginx.)
  # Sending an api-key over an unencrypted channel is insecure.
  #
  # Uncomment to enable.
  # api_key: your_secret_api_key_here

  # Set an api-key for read-only operations.
  # If set, all requests must include a header with the api-key.
  # example header: `api-key: <API-KEY>`
  #
  # If you enable this you should also enable TLS.
  # (Either above or via an external service like nginx.)
  # Sending an api-key over an unencrypted channel is insecure.
  #
  # Uncomment to enable.
  # read_only_api_key: your_secret_read_only_api_key_here

  # Uncomment to enable JWT Role Based Access Control (RBAC).
  # If enabled, you can generate JWT tokens with fine-grained rules for access control.
  # Use generated token instead of API key.
  #
  # jwt_rbac: true

cluster:
  # Use `enabled: true` to run Qdrant in distributed deployment mode
  enabled: false

  # Configuration of the inter-cluster communication
  p2p:
    # Port for internal communication between peers
    port: 6335

    # Use TLS for communication between peers
    enable_tls: false

  # Configuration related to distributed consensus algorithm
  consensus:
    # How frequently peers should ping each other.
    # Setting this parameter to lower value will allow consensus
    # to detect disconnected nodes earlier, but too frequent
    # tick period may create significant network and CPU overhead.
    # We encourage you NOT to change this parameter unless you know what you are doing.
    tick_period_ms: 100


# Set to true to prevent service from sending usage statistics to the developers.
# Read more: https://qdrant.tech/documentation/guides/telemetry
telemetry_disabled: false


# TLS configuration.
# Required if either service.enable_tls or cluster.p2p.enable_tls is true.
tls:
  # Server certificate chain file
  cert: ./tls/cert.pem

  # Server private key file
  key: ./tls/key.pem

  # Certificate authority certificate file.
  # This certificate will be used to validate the certificates
  # presented by other nodes during inter-cluster communication.
  #
  # If verify_https_client_certificate is true, it will verify
  # HTTPS client certificate
  #
  # Required if cluster.p2p.enable_tls is true.
  ca_cert: ./tls/cacert.pem

  # TTL in seconds to reload certificate from disk, useful for certificate rotations.
  # Only works for HTTPS endpoints. Does not support gRPC (and intra-cluster communication).
  # If `null` - TTL is disabled.
  cert_ttl: 3600

启动的时候通过--config-path指定config的位置

./qdrant --config-path /etc/config.yaml

2、还有一种环境变量

QDRANT__LOG_LEVEL=INFO
QDRANT__SERVICE__HTTP_PORT=6333
QDRANT__SERVICE__ENABLE_TLS=1
QDRANT__TLS__CERT=./tls/cert.pem
QDRANT__TLS__CERT_TTL=3600

QDRANT__SERVICE__HTTP_PORT=1234 ./qdrant

可以在配置文件中设置apikey，在config.yaml增加

service:
  # Set an api-key.
  # If set, all requests must include a header with the api-key.
  # example header: `api-key: <API-KEY>`
  #
  # If you enable this you should also enable TLS.
  # (Either above or via an external service like nginx.)
  # Sending an api-key over an unencrypted channel is insecure.
  api_key: your_secret_api_key_here

export QDRANT__SERVICE__API_KEY=your_secret_api_key_here

curl \
  -X GET https://localhost:6333 \
  --header 'api-key: your_secret_api_key_here'
