nano /etc/ssh/sshd_config

Add a line PermitRootLogin yes:

# Authentication:
#LoginGraceTime 2m
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

Restart the SSH server:

systemctl restart sshd

sudo du -hc --max-depth=1 /var

Find the InfluxDB configuration file in /etc/influxdb/influxdb.conf and adjust the following line:

# Determines whether HTTP request logging is enabled.
log-enabled = false

If you echo nothing to a file, it will clear the content to empty it. Just using sudo will not work, you need to be root!

sudo su
echo "" > logfile

Download the latest Ditto zip from Github and re-run docker-compose.yaml.

This folder contains an example docker-compose.yml which can be used to start Eclipse Ditto with its backing Database – MongoDB – and a reverse proxy – nginx – in front of the HTTP and WebSocket API.

Eclipse Ditto :: Docker

Source: https://github.com/eclipse/ditto/blob/master/deployment/docker/README.md

Configure nginx

The nginx’s configuration is located in the nginx.conf file and contains a “Basic authentication” for accessing the HTTP and WebSocket API. The users for this sample authentication are configured in the nginx.httpasswd file also located in this directory.

In order to add a new entry to this file, use the “openssl passwd” tool to create a hashed password:

openssl passwd -quiet
 Password: <enter password>
 Verifying - Password: <enter password>

Append the printed hash in the nginx.httpasswd file placing the username who shall receive this password in front like this:

ditto:A6BgmB8IEtPTs

Configuration of the services

You may configure each service via passing variables to the java VM in the entrypoint section for each service.

...
# Alternative approach for configuration of the service
command: java -Dditto.gateway.authentication.devops.password=foobar -jar starter.jar

To get a list of available configuration options you may retrieve them from a running instance via:

# Substitute gateway with the service you are interested in
curl http://devops:foobar@localhost:8080/devops/config/gateway/?path=ditto

Or by going through the configuration files in this repository e.g. /services/gateway/starter/src/main/resources/gateway.conf.
