I am watching a course on Hyperledger Composer development online. I installed all the required prerequisites, docker, docker-compose, nodejs, golang. After cloning the fabric-samples repository from github. There is a file called byfn.sh inside a folder called first-network. On running the command ./byfn.sh up, it's giving the following error:
If, someone has experience working on it, please help. Any help would be appreciated. Thank you.
I think the first thing you should do is stop looking at or trying to use Hyperledger Composer. It is end of life now and some of it's components will have problems even if you install the exact required versions (for example the rest server fails to launch now on node 8 but changing to a newer version of node may break other parts of Composer).
As you had planned to use it with hyperledger fabric I would suggest that you just invest your time in Hyperledger fabric, see https://hyperledger-fabric.readthedocs.io/en/latest/
Regarding your problem with docker, I suspect you tried to install docker through the apt command in your wsl window ? I'm guessing that you are using WSL2, but if you are using WSL1 then docker will never work in a WSL1 environment. If it was WSL2 then the docker daemon doesn't automatically start in that environment you need to start it yourself first. I think the command is service docker start. The important thing here is to make sure you are using WSL2 and not WSL1 (see hyperledger fabric link later which provides guidance on making sure you are using WSL2).
An alternative to installing docker into WSL2 directly would be to install Docker Desktop for Windows and follow the hyperledger fabric instructions here https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html#wsl2
Recently I faced a problem that when I open docker desktop it's automatically stopped after a few seconds. I try to solve it in several ways like reinstalling the docker desktop and also trying some methods that are available on the internet as solutions. But these do not work for me.
Is anyone can help me, please.
I have had lots of problems with installing docker on windows .
make sue you are following docker's documentation step by step.
Most of the times the problem is related to wsl2 , hyper-v or cpu virtualization. check this parameters
Docker in windows

if your installing with boot2docker place the boot2doker.iso in cache i.e c:/username/.docker/machine/cache and re-run in terminal
Can I install Docker over a server with pre-installed cPanel and CentOS 7? Since I am not aware of Docker, I am not completely sure whether it will mess with cPanel or not. I already have a server with CentOS 7 and cPanel configured. I want to know if I can install Docker over this configuration I mentioned without messing up?
Yes you can install docker over cPanel/WHM just like installing it on any other CentOS server/virtual machine.
Just follow these simple steps (as root):
1) yum install -y yum-utils device-mapper-persistent-data lvm2 (these should be already installed...)
2) yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
3) yum install docker-ce
4) enable docker at boot (systemctl enable docker)
5) start docker service (systemctl start docker)
The guide above is for CentOS 7.x. Don't expect to find any references or options related to Docker in the WHM interface. You will be able to control docker via command line from a SSH shell.
I have some docker containers already running on my cPanel/WHM server and I have no issues with them. I basically use them for caching, proxying and other similar stuff.
And as long as you follow these instructions, you won't mess-up any of your cPanel/WHM services/settings or current cPanel accounts/settings/sites/emails etc.
Not sure why you haven't tried this already!
I've been doing research and working on getting Docker working on cPanel. It's not just getting it to work on a CentOS 7 box but rather making it palatable for the cPanel crowd in the form of a plugin. So far I can confirm that it's absolutely doable. Here's what I've accomplished and how:
Integrate Docker Compose with cPanel (which is somewhat a step
further from WHM)
Leverage the user-namespace kernel feature in Linux so Docker
services can't escalate their privileges (see userns remap)
Leverage Docker Compose so users can build complex services and
start ready apps from the store with a click
Make sure services starting via Docker run on a non-public IP on the
server. Everything gets routed via ProxyPass
cPanel has been gracious to provide a Slack channel for people to discuss this upcoming plugin. I'd be more than happy to invite you if you'd like to be kept updated or to contribute. Let me know!
FYI, there's more info here on https://www.unixy.net/docker if you're interested. Please note that this plugin is in private beta but more than happy to let people use it!
Yes you could, in fact someone else has done it already: https://github.com/mirhosting/cPanel-docker
This morning I've started playing with Docker, so installed boot2docker on my Mac.
All seemed to be going well, following the Working with Docker Images documentation until I tried to create a Dockerfile to install the ruby gems.
I spent a long time banging my head against the wall as to why it couldn't connect to install the gems... then I eventually worked it out, so adding this here in case anyone else has this problem in future, as there wasn't anything on Google about it.
Turns out that, because my internet bombed out during the apt-get update command, it didn't complete the update, however running it again, docker was using the cached (incomplete) data, and so if didn't work.
The fix... Run the docker build without the cache using the command...
docker build -no-cache --tag="<vendor>/<build>:<tag>" .
