Docker Image Quickstart

Capabilities

This image currently supports running in standalone mode either unsecured or with user authentication provided through:

• Two-Way SSL with Client Certificates
• Lightweight Directory Access Protocol (LDAP)

Building

The Docker image can be built using the following command:

# user @ puter in ~/path/to/apache/nifi-registry/nifi-registry-docker/dockerhub    
$ docker build -t apache/nifi-registry:latest .

This will result in an image tagged apache/nifi:latest

$ docker images
> REPOSITORY               TAG           IMAGE ID            CREATED                  SIZE
> apache/nifi-registry     latest        751428cbf631        A long, long time ago    342MB

Note: The default version of NiFi Registry specified by the Dockerfile is typically that of one that is unreleased if working from source. To build an image for a prior released version, one can override the NIFI_REGISTRY_VERSION build-arg with the following command:

$ docker build --build-arg NIFI_REGISTRY_VERSION={Desired NiFi Registry Version} -t apache/nifi-registry:latest .

There is, however, no guarantee that older versions will work as properties have changed and evolved with subsequent releases. The configuration scripts are suitable for at least 0.1.0+.

Running a container

Standalone Instance, Unsecured

The minimum to run a NiFi Registry instance is as follows:

docker run --name nifi-registry \
  -p 18080:18080 \
  -d \
  apache/nifi-registry:latest

This will provide a running instance, exposing the instance UI to the host system on at port 18080, viewable at http://localhost:18080/nifi-registry.

You can also pass in environment variables to change the NiFi Registry communication ports and hostname using the Docker '-e' switch as follows:

docker run --name nifi-registry \
  -p 19090:19090 \
  -d \
  -e NIFI_REGISTRY_WEB_HTTP_PORT='19090'
  apache/nifi-registry:latest

For a list of the environment variables recognised in this build, look into the .sh/secure.sh and .sh/start.sh scripts

Standalone Instance, Two-Way SSL

In this configuration, the user will need to provide certificates and the associated configuration information. Of particular note, is the AUTH environment variable which is set to tls. Additionally, the user must provide an the DN as provided by an accessing client certificate in the INITIAL_ADMIN_IDENTITY environment variable. This value will be used to seed the instance with an initial user with administrative privileges. Finally, this command makes use of a volume to provide certificates on the host system to the container instance.

docker run --name nifi-registry \
  -v /path/to/tls/certs/localhost:/opt/certs \
  -p 18443:18443 \
  -e AUTH=tls \
  -e KEYSTORE_PATH=/opt/certs/keystore.jks \
  -e KEYSTORE_TYPE=JKS \
  -e KEYSTORE_PASSWORD=QKZv1hSWAFQYZ+WU1jjF5ank+l4igeOfQRp+OSbkkrs \
  -e TRUSTSTORE_PATH=/opt/certs/truststore.jks \
  -e TRUSTSTORE_PASSWORD=rHkWR1gDNW3R9hgbeRsT3OM3Ue0zwGtQqcFKJD2EXWE \
  -e TRUSTSTORE_TYPE=JKS \
  -e INITIAL_ADMIN_IDENTITY='CN=AdminUser, OU=nifi' \
  -d \
  apache/nifi-registry:latest

Standalone Instance, LDAP

In this configuration, the user will need to provide certificates and the associated configuration information. Optionally, if the LDAP provider of interest is operating in LDAPS or START_TLS modes, certificates will additionally be needed. Of particular note, is the AUTH environment variable which is set to ldap. Additionally, the user must provide a DN as provided by the configured LDAP server in the INITIAL_ADMIN_IDENTITY environment variable. This value will be used to seed the instance with an initial user with administrative privileges. Finally, this command makes use of a volume to provide certificates on the host system to the container instance.

For a minimal, connection to an LDAP server using SIMPLE authentication:

docker run --name nifi-registry \
  -v /path/to/tls/certs/localhost:/opt/certs \
  -p 18443:18443 \
  -e AUTH=ldap \
  -e KEYSTORE_PATH=/opt/certs/keystore.jks \
  -e KEYSTORE_TYPE=JKS \
  -e KEYSTORE_PASSWORD=QKZv1hSWAFQYZ+WU1jjF5ank+l4igeOfQRp+OSbkkrs \
  -e TRUSTSTORE_PATH=/opt/certs/truststore.jks \
  -e TRUSTSTORE_PASSWORD=rHkWR1gDNW3R9hgbeRsT3OM3Ue0zwGtQqcFKJD2EXWE \
  -e TRUSTSTORE_TYPE=JKS \
  -e INITIAL_ADMIN_IDENTITY='cn=nifi-admin,dc=example,dc=org' \
  -e LDAP_AUTHENTICATION_STRATEGY='SIMPLE' \
  -e LDAP_MANAGER_DN='cn=ldap-admin,dc=example,dc=org' \
  -e LDAP_MANAGER_PASSWORD='password' \
  -e LDAP_USER_SEARCH_BASE='dc=example,dc=org' \
  -e LDAP_USER_SEARCH_FILTER='cn={0}' \
  -e LDAP_IDENTITY_STRATEGY='USE_DN' \
  -e LDAP_URL='ldap://ldap:389' \
  -d \
  apache/nifi-registry:latest

The following, optional environment variables may be added to the above command when connecting to a secure LDAP server configured with START_TLS or LDAPS

-e LDAP_TLS_KEYSTORE: ''
-e LDAP_TLS_KEYSTORE_PASSWORD: ''
-e LDAP_TLS_KEYSTORE_TYPE: ''
-e LDAP_TLS_TRUSTSTORE: ''
-e LDAP_TLS_TRUSTSTORE_PASSWORD: ''
-e LDAP_TLS_TRUSTSTORE_TYPE: ''
