Overview

Synthetic private locations come with a set of options you can configure to match your environment requirements. All options for the private location worker can be found by running the help command:

docker run --rm datadog/synthetics-private-location-worker --help
synthetics-private-location.exe --help

Customize your private location

Available parameters are listed below. These configuration options for private locations can be passed as parameters to your JSON configuration file or as arguments in the launch command, for example:

docker run --rm -v $PWD/<MY_WORKER_CONFIG_FILE_NAME>.json:/etc/datadog/synthetics-check-runner.json datadog/synthetics-private-location-worker:latest --logFormat=json
synthetics-private-location.exe --config=<PathToYourConfiguration> --logFormat=json

Arguments set in the launch command have precedence over the configuration file. However, these options are not stored and are consequently only relevant for a given launch.

Top configuration options

Datadog site configuration

site
Type: String
Default: datadoghq.com
Datadog site from which the private location pulls the test configuration and pushes the test results. Your site is .

DNS configuration

The following parameters can be used to customize DNS resolution on your API tests:

dnsUseHost
Type: Boolean
Default: true
Use host local DNS configuration first (for example, the configuration from your etc/resolv.conf file), then DNS servers specified in the dnsServer parameter.
dnsServer
Type: Array of Strings
Default: ["8.8.8.8","1.1.1.1"]
DNS servers IPs to use in given order (for example, --dnsServer="8.8.4.4" --dnsServer="8.8.8.8").

On browser tests, the DNS resolution is done directly by the browser, which usually reads DNS servers from the host. Alternatively, you can configure it at the container level (for example, using the --dns flag on Docker, or dnsConfig.nameservers on Kubernetes).

Proxy configuration

proxyDatadog
Type: String
Default: none
Proxy URL used by the private location to send requests to Datadog (for example, --proxyDatadog=http://<YOUR_USER>:<YOUR_PWD>@<YOUR_IP>:<YOUR_PORT>).
proxyTestRequests
Type: String
Default: none
Proxy URL used by the private location to send test requests to the endpoint. PAC files are supported with the following syntax: pac+https://... or pac+http://....
proxyIgnoreSSLErrors
Type: Boolean
Default: false
Discard SSL errors when private location is using a proxy to send requests to Datadog.

Note: The proxy parameter is deprecated and should be replaced by proxyDatadog.

Advanced configuration

concurrency
Type: Number
Default: 10
Maximum number of tests executed in parallel.
maxNumberMessagesToFetch
Type: Number
Default: 10
Maximum number of tests fetched from Datadog.

Note: Private Location containers output logs to stdout and stderr without saving them within the container.

All configuration options

--accessKey
Type: String
Default: none
Access key for Datadog API authentication.
--secretAccessKey
Type: String
Default: none
Secret access key for Datadog API authentication.
--datadogApiKey
Type: String
Default: none
Datadog API key to send browser tests artifacts (such as screenshots).
--privateKey
Type: Array
Default: none
Private key used to decrypt test configurations.
--publicKey
Type: Array
Default: none
Public key used by Datadog to encrypt test results. Composed of --publicKey.pem.
--site
Type: String
Default: datadoghq.com
Datadog site from which the private location pulls the test configuration and pushes the test results. Your site is .
--concurrency
Type: Number
Default: 10
Maximum number of tests executed in parallel.
--maxNumberMessagesToFetch
Type: Number
Default: 10
Maximum number of tests fetched from Datadog.
--proxyDatadog
Type: String
Default: none
Proxy URL used by the private location to send requests to Datadog (for example, --proxyDatadog=http://<YOUR_USER>:<YOUR_PWD>@<YOUR_IP>:<YOUR_PORT>).
--disableFipsCompliance
Type: Boolean
Default: false
Disables the FIPS compliance for a private location using ddog-gov.com. By default, Private Locations reporting to ddog-gov.com communicate to Datadog using FIPS-compliant encryption. The communication complies on the use of FIPS 140-2 validated Cryptographic Module - Certificate #4282.
--dumpConfig
Type: Boolean
Default: none
Display worker configuration parameters without secrets.
--enableStatusProbes
Type: Boolean
Enables the readiness and liveness of private location probes. This enables two endpoints: http://127.0.0.1:8080/liveness and http://127.0.0.1:8080/readiness.
--statusProbesPort
Type: Number
Default: 8080
Overrides the port for the private location status probes.
--config
Type: String
Default: /etc/datadog/synthetics-check-runner.json
Path to the JSON configuration file.
--proxyTestRequests
Type: String
Default: none
Proxy URL used by the private location to send test requests to the endpoint. PAC files are supported with the following syntax: pac+https://... or pac+http://....
--proxyIgnoreSSLErrors
Type: Boolean
Default: false
Discard SSL errors when private location is using a proxy to send requests to Datadog.
--dnsUseHost
Type: Boolean
Default: true
Use host local DNS configuration first (for example, the configuration from your etc/resolv.conf file), then DNS servers specified in the dnsServer parameter.
--dnsServer
Type: Array of Strings
Default: ["8.8.8.8","1.1.1.1"]
DNS servers IPs to use in given order (for example, --dnsServer="8.8.4.4" --dnsServer="8.8.8.8").
--variableOverride
Type: String
Overrides the variables used in tests running on the Private Location. Format: VARIABLE=value. All variables imported this way are obfuscated.
--environmentVariableOverride
Type: String
Overrides variables used in tests running on the Private Location with environment variables. It requires the environment variables to be imported in the containerized environment. With Docker, for example, docker run --env VARIABLE gcr.io/datadoghq/synthetics-private-location-worker --environmentVariableOverride VARIABLE. All variables imported this way are obfuscated.
--allowedIPRanges
Type: Array of Strings
Default: none
Grant access to specific IPs and/or CIDR among IP ranges blocked through --enableDefaultBlockedIpRanges or blockedIPRanges (for example, "allowedIPRanges.4": "10.0.0.0/8"). Note: allowedIPRanges has precedence over blockedIPRanges.
--blockedIPRanges
Type: Array of Strings

Block access to specific IPs and/or CIDR in addition, or not, to the IP ranges blocked when setting the --enableDefaultBlockedIpRanges parameter to true (for example, --blockedIPRanges.4="127.0.0.0/8" --blockedIPRanges.6="::1/128".)
--enableDefaultBlockedIpRanges

Default: none
Deny access to domain names in tests, for example: --blockedDomainNames="example.org" --blockedDomainNames="*.com".
--enableIPv6
Type: Boolean

--version
Type: Boolean
Default: none
Show version number of the worker.
--logFormat
Type: String
Default: pretty
Format log output between "compact", "pretty", "pretty-compact", and "json". Setting your log format to json allows you to have these logs automatically parsed when collected by Datadog.
--verbosity
Type: Number
