I'm trying to access my redis database via Grafana Cloud on my laptop. The database is a redis container working as a cache on a different device (pi). Accessing the Redis database via Python script on my remote device is no problem but trying to connect to it via Grafana (using Redis Datasource Plugin) doesn't work as intended and throws a connection error. Poorly the documentation leaves me kinda clueless whats the specific cause (any missing plugin dependencies?) so I'm thankful for every hint.
To be able to access Redis Server from Grafana Cloud it should be exposed to the Internet as Jan mentioned.
If you run Grafana in Docker container it should be started in the host network mode (https://docs.docker.com/network/host/) to be able to access it from other devices.
If something is lacking or not clear in the Redis plugins documentation, please open an issue and we will update it: https://github.com/RedisGrafana/RedisGrafana/issues

I want to setup a local IMAP server within my home network for archiving emails. The server does not need to be accessable via the internet. Therefore I can pass on a secured access via SSL (If this makes it easier). I want to integrate the server in my current docker setup. So the server has to run within a docker container.
I already tried the following containers:
https://hub.docker.com/r/blackflysolutions/dovecot
https://hub.docker.com/r/dovecot/dovecot
https://hub.docker.com/r/mailu/dovecot
https://hub.docker.com/r/mailcow/dovecot
https://hub.docker.com/r/eilandert/dovecot
But i could not get any of them to run. At the same time none of them have a forum or anything where I can put a question. Two of them (mailu/dovecot and mailcow/dovecot) are part of a bigger mailserver package. Which I do not need, I only want a IMAP server to put some email locally. But I tried them anyway.
Does anyone know how to get any of those to run? Or suggest me another stable docker container solution.
I am currently running latest versions Nifi and Postgresql via docker compose.
as of 1.14 version update of Nifi, when you accesss the UI on web it connects via https, thus asking you for ID and Password every time you log in. Its too cumbersome to go to nifi-app.log file and look for credentials every time I access the UI. I know that you can change the setting where it keeps https as the default method but I am not sure how to do that in a docker container. Can anyone help me with this?
You could use some env like AUTH in the documentation
You can find the full explanations here
I am a beginner in regards to ArangoDB and I am trying to deploy my first project using it. The website is PHP based - what I did is that I created an Arango Docker container on Digital Ocean so that I can access it from the browser with the ipv4 provided. Public access to port 8529 is enabled. Locally, I am able to modify the .config file in order to point to the corresponding ip and I can painlessly retrieve data.
As a hosting provider I am using one.com. When uploading the same files that I am able to run locally on my own domain I get the following error:
["_database":"ArangoDBClient\Connection":private]=> string(7) "_system" } ArangoDBClient\ConnectException: cannot connect to endpoint 'tcp://xxx.xx.xxx.xxx:8529/': Connection timed out
I want to mention that I have also tried out ArangoOasis. No luck with it - I get the same error. Been at it for quite a few weeks - I would very much use some guidance. Even what to do next as I am out of ideas and documentation to read.
I am having difficulties deploying Neo4j official docker image https://hub.docker.com/_/neo4j to an OpenShift environment and accessing it from outside (from my local machine)
I have performed the following steps:
oc new-app neo4j
Created route for port 7474
Set up the environment variable NEO4J_dbms_connector_bolt_listen__address to 0.0.0.0:7687 which is the equivalent of seting up the dbms.connector.bolt.listen_address=0.0.0.0:7687 in the neo4j.conf file.
Access the route url from local machine which will open the neo4j browser which requires authentication. At this point I am blocked because any combination of urls I try are unsuccessful.
As a workaround I have managed to forward 7687 port to my local machine, install Neo4j Desktop solution and connect via bolt://localhost:7687 but this is not the ideal solution.
Therefore there are two questions:
1. How can I connect from the neo4j browser to it's own database
How can I connect from external environment (trough OpenShift route) to the Neo4j DB
I have no experience with the OpenShift, but try to add the following config:
dbms.default_listen_address=0.0.0.0
Is there any other way for you to connect to Neo4j, so that you could further inspect the issue?
Short answer:
To connect to the DB that is most likely a configuration issue, maybe Tomaž Brataničs answer is the solution. As for accessing the DB from outside, you will most likely need a NodePort.
Long answer:
Note that OpenShift Routes are for HTTP / HTTPS traffic and not for any other kind of traffic. Typically, the "Routers" of an OpenShift cluster listen only on Port 80 and 443, so connecting to your database on any other port will most likely not work (although this heavily depends on your cluster configuration).
The solution for non-HTTP(S) traffic is to use NodePorts as described in the OpenShift documentation: https://docs.openshift.com/container-platform/3.11/dev_guide/expose_service/expose_internal_ip_nodeport.html
Note that also for NodePorts, you might need to have your cluster administrator add additional ports to the loadbalancer or you might need to connect to the OpenShift Nodes directly. Refer to the documentation on how to use NodePorts.
I have kapua (as a docker container on my pc) and kura on the raspberryPi.
I managed to connect them, to run the example publisher and to correctly receive the data on kapua.
Now I would like to view the data via graphana (docker container) by linking this to kapua's elasticsearch (container docker).
I tried to link them indicating the address of elastichsearch localhost:9200 and to enter the credentials of kapua but it continues to give error 502 bad gateway.
Could anyone help me?
Thanks in advance.
By default Elasticsearch in Kapua has no credential.
The capability of configure them is not yet released and it has been introduced with https://github.com/eclipse/kapua/pull/2685. It will be released in Kapua 1.1.0
Have you tried without credentials?
