Environment

1. OS : Ubuntu 22.04.4 LTS
2. OpenCTI version: 6.2.7
3. OpenCTI client: python

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Complete setup using docker in Linux VM. Setup documentation
2. After running the custom connector with the python. I get an this issue. I have provided all groups and user to all TLP.
3. Error

Expected Output

The data should be inserted and displayed in the Observable objects.
The dashboard should have observable objects.

Actual Output

1. Ingestion - connectors shows the activity log but it always show in-progress.

2. The Observable objects are empty here.

3. The activity log contains these activity.

Additional information

1. I have given the bypass permission ( admin level permission ) to all groups and users.
2. Whenever I run the main.py the docker image of the custom_connector is not running as I have check with docker ps command.
3. Can you help me to correct main.py. Complete log is given here.

Hello @meetghodasara: It seems that your connector is not able to connect to RabbitMQ.
First option, try running your “connector container” in the same docker context as OpenCTI (same docker-compose.yml).
Second option: you need to expose the rabbitmq port and add DNS resolution to resolve “rabbitmq”.

[meetghodasara]

Thanks you @romain-filigran .

I am tried these steps but still unable to resolve the issue.

1. Using the custom connector docker compose , I have build image of the custom connector.
2. I have add that image as the docker compose of Docker Setup for OpenCTI
3. After re-start the docker compose of OpenCTI , I got same error as here
   IMPORTANT (OpenCTI docker installation does not work  docker#81)

4. Here is the log of custom connector running on docker.

5. When I run the main.py of the connector after docker compose of OpenCTI. I get the given below error.

Can you share your docker configuration of the connector. The error is different from the previous one. If your connector is now in the same docker context, you certainly need to change the “OPENCTI_URL” variable in your connector configuration to point to: http://opencti:8080 instead of http://localhost:8080

[meetghodasara]

Here is the docker configuration of the connector.

version: '3'

Using this command, I have build an docker image.
docker build -t opencti/connector-myconnector .

OpenCTI API is not reachable. Waiting for OpenCTI API to start or check your configuration...

[romain-filigran]

it seems that the elasticsearch container does not start ("Search engine seems down"). Please check its logs

[meetghodasara]

First of all Thank you so much @romain-filigran and OpenCTI community.

Yes it was Search engine seems down. As I was normally docker-compose command so it wasn't solved but with Portainer. It is solved. Seems like some network problem was there.

I have completed solved issue #2398
with the following steps.

Pre-configuration

1. Set the VM size for Elastic search with the given command
   sudo sysctl -w vm.max_map_count=1048575
2. Every UUID should be generated from the UUID Generator website
3. Use Docker Swarm and Portainer to configuration of OpenCTI.

Installation steps

1. I have did the installation of Docker, Creation of Docker Swarm , and configuration of Portainer from the given article. Also here is the video tutorial for the same.

2. Custom connector configuration is as follow.
   Here is the docker-compose.yaml

opencti:
  url: "http://opencti:8080"
  token: 396187c1-82c7-4fae-bb99-21e1591eb02e


connector:
  id: 2f3558fc-6eb7-413f-9ae0-5cab8a38cbab
  type: 'EXTERNAL_IMPORT'
  name: 'myconnector'
  scope: 'identity,attack-pattern,course-of-action,intrusion-set,malware,tool,report,vulnerability,campaign,incident,indicator,infrastructure,location,note,threat-actor,tool,software'
  run_and_terminate: false
  log_level: 'info'
 
myconnector:

with using docker-compose build for building of docker image.

Portainer Stack Configuration

3. The given below is docker-compose for the OpenCTI.
   IMPORTANT > docker compose

4. The given below is .env file for the OpenCTI docker-compose. (Note: these uuid generated from UUID Generator website )

5. Here is the our custom connector is running successfully with the data shown in dashboard.

Your Custom connector can be found here Data>Ingestion>Connector>myconnector.

Sample data shown in dashboard that are injected through myconnector.

Other issues I had got during setup that are solved with the above method.

1. Elastic Search seems down in OpenCTI Platform container. | (ElasticSearch seems down  opencti#1412)
2. Data not displayed in Dashboard after Docker Installation of OpenCTI. | (OpenCTI docker installation does not work  docker#81)
3. RabbitMQ Pika Connection error. AMPQ Connection workflow failed. | (RabbitMQ connexion doesn't work (example MISP) #54)
4. GraphQL Http Connection Error. Failed to establish a new connection, connection refused | (Worker HTTP Connection Problem opencti#155)
5. OpenCTI API is not reachable. Waiting for OpenCTI API to start or check your configuration... | (Docker Containers Failing to start upon initial install opencti#5159)

I am using version 6.2.6 and used this guy video you sent.

I am getting this is the error with alienvault connector: @meetghodasara

During handling of the above exception, another exception occurred:

Could you please share your docker-compose and .env file?
Also please share the log of OpenCTI platform container.

I have written one article about Installation of OpenCTI using Docker so you can refer it too.
Installing OpenCTI with Docker: A Step-by-Step Guide

You can refer the my docker compose and .env.sample file from the given Docker-Github

Reading this thread makes me understand that issue is solved. I'm closing this ticket, but feel free to re-open it if needed.
