Hi guys I'm using Hyperledger Fabric network and Blockchain explorer.
I tested explorer for "first-network" and I succeeded. After that because I wanted to build multi-machine Fabric network, I referred to https://medium.com/#wahabjawed/hyperledger-fabric-on-multiple-hosts-a33b08ef24f And to do the test I ran all docker container(CA, ORDERER, 2PEERS, CLI) into local machine and edited config.json file as below

And I got error. there is error log below

Is there anybody who knows how to solve this problem?
I was facing the same problem as you post when I tried to connect Hyperledger Explorer to basic-network example.
I found this post in link below and it can solve my problem, hope it can help you too.
Unable to setup hyperledger explorer with one node (like basic network example)

I'm trying to use the chaos toolkit istio extension, my problem is as follows:
I have a experiment.json file which contains a single probe to retrieve a virtual service. The file looks similar to the following:
{
"version": "1.0.0",
"title": "test",
"description": "N/A",
"tags": []
"secrets": {
"istio": {
"KUBERNETES_CONTEXT": {
"type": "env",
"key": "KUBERNETES_CONTEXT"
}
}
},
"method": [
{
"type": "probe",
"name": get_virtual_service:,
"provider": {
"type": "python",
"module": "chaosistio.fault.probes",
"func": "get_virtual_service",
"arguments": {
"virtual_service_name": "test"
"ns": "test-ns"
}
}
}
}
I have set KUBERNETES_CONTEXT and http/https proxy as env vars. My authorisation is using $HOME/.kube/config.
When playing the experiment it validates the file fine and tries to perform the action but becomes stuck and just hangs until it times out.
The error I see in the logs is a HTTPSConnectionPool error (failed to establish a new connection, operation timed out).
Am I missing any settings? All help appreciated.
I have a requirement where I need to read message from one rabbit mq and publish it to another.
I tried configuring both the host, but when i publish it publishes only to the first configured rabbit mq.
I got the multibus running but now I am stuck with healthcheck
Both of the bus are returning status under IBus
{
"status": "Unhealthy",
"results": {
"IBus": {
"status": "Healthy",
"description": "Ready",
"data": {
"Endpoints": {
"rabbitmq://localhost:5672/XXXXX_Sxxxxxxx_bus_39pyyy81rrcpzwhibdcedd8sno?temporary=true": {
"Message": "ready (not started)"
},
"rabbitmq://localhost:5673/XXXXX_Sxxxxxxx_bus_39pyyy81rrcpzwhibdcedd8sno?temporary=true": {
"Message": "ready (not started)"
},
"rabbitmq://localhost:5673/xxxxxConsumer": {
"Message": "ready"
},
"rabbitmq://localhost:5672/xxxxxx--xxxxxConsumer": {
"Message": "ready"
}
}
}
},
"IRabbitMqBusB": {
"status": "Unhealthy",
"description": "Not ready: not started",
"data": {
"Endpoints": {}
}
}
}
}
It's called MultiBus and thoroughly described in the documentation.
In addition, it doesn't "publish to the first configured bus". It only does that if you use a DI container and use the resolved IPublishEndpointProvider. Since it's registered as a singleton with Try, you won't get the second instance registered.
If you don't use the DI container and use the bus instance, you can do whatever you want. The MultiBus feature allows you to use multiple bus instances registered in the container.
I have a RabbitMQ queue that is declared with the following options:
{
"queue": "events/online",
"durable": true,
"args": {
"x-max-priority": 10
}
}
I am trying to connect to the queue from Node-RED, using the node-red-contrib-amqp plugin, with the following Topology that is set under the connection source:
{
"queues": [
{
"name": "events/online",
"durable": true,
"options": {
"x-max-priority": 10
}
}
]
}
I am getting the following error:
"AMQP input node disconnect error: Operation failed: QueueDeclare; 406
(PRECONDITION-FAILED) with message "PRECONDITION_FAILED - inequivalent
arg 'x-max-priority' for queue 'myqueue' in vhost 'vhost': received
none but current is the value '10' of type 'signedint'""
Turns out the answer is as follows.
Make sure the following checkbox is selected: "use AMQP topology definition (JSON) defined below"
{
"queues": [
{
"name": "events/online",
"durable": true,
"options": {
"maxPriority": 10
}
}
]
}

i have a problem with remote connections.
my vhost is : redis.test
i added this on blade file:
<script src="//redis.test:6001/socket.io/socket.io.js"></script>
.env file
BROADCAST_DRIVER=redis
REDIS_HOST=redis.test
REDIS_PASSWORD=null
REDIS_PORT=6379
echo configuration
import Echo from "laravel-echo"
window.Echo = new Echo({
broadcaster: 'socket.io',
host: 'http://redis.test:6001'
});
laravel-exho-server.json
{
"authHost": "http://redis.test",
"authEndpoint": "/broadcasting/auth",
"clients": [
{
"appId": "f27485125ac2627f",
"key": "6328e672f42cbf4cba1de3da215ec41a"
}
],
"database": "redis",
"databaseConfig": {
"redis": {
"port": "6379",
"host": "redis.test"
},
"sqlite": {
"databasePath": "/database/laravel-echo-server.sqlite"
}
},
"devMode": true,
"host": "redis.test",
"port": "6001",
"protocol": "http",
"socketio": {},
"sslCertPath": "",
"sslKeyPath": ""
}
it works when i try to broadcast with a local connection (2 browsers - same pc), but when i try to send a "message" from other pc on lan network (192.168.1.50) i have this error
GET: http://redis.test:6001/socket.io/socket.io.js net::err_connection_refused
[vue_warn] error in created hook
how ca i resolve this?
It may be a firewall issue as I can see, try to open redis port in the firewall
