Liquibase Hub Properties

Liquibase Hub has a list of properties to be set so that your local Liquibase activity is reported to a specific Liquibase Hub Project.

Required properties

Specifying the Liquibase Hub API Keys is the required property to connect to Liquibase Hub along with a registered changelog file.

There are three ways to specify your API Key:

  1. Including liquibase.hub.ApiKey value in the liquibase.properties file:
liquibase.hub.ApiKey: <addYourHubApiKeyHere>

An example of the liquibase.properties file with the Liquibase Hub API Key

# liquibase.properties
changeLogFile: ../path/to/file/dbchangelog.xml
driver: oracle.jdbc.OracleDriver
url: jdbc:oracle:thing:@192.168.0.22:1521/orcl
username: PRO
password: password
referenceDriver: oracle.jdbc.oracleDriver
referenceurl: jdbc:oracle:thin:@192.168.0.22:1521/orcl
referencePassword: password
liquibaseProLicenseKey: <addYourProLicenseKeyHere>
classpath: ../path/to/file/ojdbc6-11.2.0.3.0.jar
# Add Your First Liquibase Hub API Key
liquibase.hub.ApiKey: <addYourHubApiKeyHere>
  1. Passing liquibaseHubApiKey on the command line:
--liquibaseHubApiKey=addYourHubApiKeyHere

An example of the Liquibase Hub API Key running on the command line

java -jar liquibase.jar \
--driver=oracle.jdbc.Oracleoriver \
--classpath=../path/to/file/ojdbc6-11.2.0.3.0.jar \
--changeLogFile=com/example/db.changelog.xml \
--url="jdbc:oracle:thing:@192.168.0.22:1521/orcl" \
--username=scott \
--password=tiger \
--liquibaseProLicenseKey=<addYourProLicenseKeyHere>\
--liquibaseHubApiKey=<addYourHubApiKeyHere>\
update
  1. Specifying API key in your JAVA_OPTS Environment Variable as -Dliquibase.hub.apikey.
    1. On Linux or MacOS: JAVA_OPTS="-Dliquibase.hub.apikey=<myapikey>"
    2. On Windows: set JAVA_OPTS="-Dliquibase.hub.apikey=<myapikey>"

Note: You can also manually set JAVA_OPTS as an environment variable in your system.

Optional properties

The Liquibase Hub URL, which is https://hub.liquibase.com, is specified by default when you sign up for an account and connect to Liquibase Hub with the API Key.

There are two ways to change the location property, select one of the following two options:

  • Include liquibaseHubUrl value in the liquibase.properties file:
liquibaseHubUrl:https://hub.liquibase.com
  • Specify URL in your JAVA_OPTS Environment Variable as -DliquibaseHubUrl: 
    • On Linux or MacOS: JAVA_OPTS="-Dliquibase.hub.url=https://hub.liquibase.com"
    • On Windows: set JAVA_OPTS="-Dliquibase.hub.url=https://hub.liquibase.com"

Note: You can also manually set JAVA_OPTS as an environment variable in your system.

Another optional property is liquibase.hub.mode, which represents the level of data you want to send to Liquibase Hub. The default value is: all.

liquibase.hub.mode:[all=default|meta|off]
Liquibase Hub mode Definition

all

Sends all data, including the changeset body, generated SQL, and logs (the default value)

meta

Does not send the changeset body, generated SQL, or operation-event and change-event logs

off

Does not send any data to Liquibase Hub

To specify the level of data, select one of the following options:

  • Include liquibase.hub.mode value in the liquibase.properties file:
liquibase.hub.mode:meta
  • Specify the Liquibase Hub mode in your JAVA_OPTS Environment Variable as -DLiquibaseHubMode: 
    • On Linux or MacOS: JAVA_OPTS="-DliquibaseHubMode=[all|meta|off]"
    • On Windows: set JAVA_OPTS="-DliquibaseHubMode=[all|meta|off]"

Note: You can also manually set JAVA_OPTS as an environment variable in your system.

Additionally, you can have different Liquibase Hub mode settings for different connections.

For example, if sensitive DML updates are only made to the PROD connection and not to lower-level connections, you can have PROD in the meta mode and all lower connections in the all mode.

You can specify the liquibase.hub.mode in your liquibase.properties file, as a system property with -DliquibaseHubMode, as an environment variable LIQUIBASE_HUB_MODE, or store it in a liquibase.prod.properties file.

If you specify the Liquibase Hub mode only in one place, Liquibase will use it as the default. If you have the Liquibase Hub mode specified in multiple places, Liquibase will use the following order of precedence to determine which value to use:

  • The liquibase.prod.properties file
  • The liquibase.properties file
  • The LIQUIBASE_HUB_MODE environment variable, which overrides all of the preceding places

If you have policies and compliance requirements that prohibit sensitive information (PII or HIPAA) from leaving the controlled domain, use liquibase.hub.mode=meta. The meta mode is recommended if your scripts contain data that is regulated by government compliance standards, such as HIPAA, PCI, and others.
