I have multiple laptops at home, and I want to use one of them as a master and the rest as workers.
How do I connect them ?
Should I Install Spark On all machines ?
Should I Install Kubernetes On all machines ?
Basically how does this work ? I am lost and would love to get a roadmap !
Note : Don't bother yourself by giving me the full technical roadmap (commands etc ..), I only need the steps and relevant articles in the right order because I feel lost.
Thank you in advance.
I am new to the tech world, I want to get to know eclipse hawkBit, I am a total noob and beginner so any help is mucha appreciated.
My scenario:
I have a Windows 10 OS with VMware workstation on it, I have installed Ubuntu on it to run eclipse hawkBit and docker ofcourse.
My internet connection is a highspeed mobile internet connection, I use my smarphone to tether(Mobile hotspot).
What I want to do:
I want to start eclipse hawkBit so basically run it simulate some devices and get to know how to use hawkBit.
My problem: so to run hawkBit according to the official documentation i just need to give this on the terminal: docker run -p 8080:8080 hawkbit/hawkbit-update-server:latest
I have seen a youtube video where if hawkBit works it will show me the localhost port info and say successfully connected(or something similar to that)
but the error or problem i keep encountering is this: 2021-06-17 11:35:19.312 INFO 1 --- [tContainer#1-56] o.s.a.r.c.CachingConnectionFactory : Attempting to connect to: [localhost:5672]
Here is a picture of it:
I would really appreciate if you guys could help me with this, there is not much support or videos of this problem, infact its hard to find decent reference material for hawkBit.
any help is much appreciated.
The exception you see here is due to a missing (or misconfigured) RabbitMQ service.
You will need to configure the environment variable SPRING_RABBITMQ_HOST to point to the running RabbitMQ instance.
docker run -p 8080:8080 -e SPRING_RABBITMQ_HOST=ip-of-rabbitmq-service hawkbit/hawkbit-update-server:latest
For an easier setup, you could use the docker compose file for hawkbit (Option B or C), which already has a preconfigured RabbitMQ as well as MySQL container.
I was trying to build OpenVPN with Microsoft Azure but having problems now...
After adding inbound rules I am able to connect to the server now but something get weird here since I am not able to visit any websites e.g. google.com, amazon.com, etc. Then I searched online and eventually found out that I did not have my route table configured yet. I have tried to configure it myself but failed after many attempts, need some help here.
I would appreciate it a lot if someone can help my resolve the problem since it is driving me crazy.
Great thanks!
Using Ubuntu 16.04
OpenVPN 2.3.7
I only added one route to the route table - Name: GatewaySubnet; Address Prefix:10.0.3.0/27; Next Hop:Virtual network gateway
and a subnet: NAME: default; Address range:10.0.0.0/24...
Do not have access to the internet after connecting to OpenVPN server build with Microsoft Azure
I would like to first create a Digital Ocean droplet(server) and then create multiple docker containers for various services inside that server.
I feel like this should be easy but I cannot find any examples of others doing this. Any help would be greatly appreciated.
You cannot really nest resources like that in Terraform. You have a two different ways to approach this, I would use the user_data argument that will run a script on your droplet that will issue the docker commands to pull down your container images and start your containers. Here is a blog post with an example.
Hope this helps.
I'm docker newbie. 'm running mongoDB in a container and redisDB in an other container and i'm linking this tow databases to my nodeJS project wich is running in a third container. In order to connect to my databases i'm putting the IPs of my containers in my source code but everytime i'm restarting a container the IP is changing so i have to change it in my source code,How can i deal with this problem?
as Michael just said, you can specify an IP Address via the "--ip" parameter
Example :
docker run -d --name="mongoDB" --ip=172.10.0.1 -p=12720:12720 imageIdOrTagName
(Don't forget it is "--ip" and not "-ip)
For further information, please consider reading the "Docker Networking Documentation" page.
If you have any other questions, feel free to ask.
EDIT For Docker < 1.10:
This github issue references what you are asking :
Allow user to choose the IP address for the container
It has been integrated in Docker 1.10.0 trough the "docker run --ip=..." command
For older versions, itoffshore presented a temporary solution right here.
Hope it will help.
Have a good day,
Nicolas.
You can specify the IP address of the container in the docker run command line with --ip="<ip address>"
