Running the network

export MICROFAB_CONFIG='{
"port": 8080,
"endorsing_organizations":[
{
"name": "ProducersOrg"
},
{
"name": "SellersOrg"
}
],
"channels":[
{
"name": "mango-channel",
"endorsing_organizations":[
"ProducersOrg",
"SellersOrg"
]
}
]
}'

docker run -e MICROFAB_CONFIG -p 8080:8080 ibmcom/ibp-microfab

Or

sudo docker run --name microfab --rm -ti -p 8080:8080 -e MICROFAB_CONFIG="${MICROFAB_CONFIG}" ibmcom/ibp-microfab

1. Create wallet & Gateways:

• 1. Try a different ISP, if it is Jio India.
  2. Use a different DNS:
  • 1. Run: sudo nano /etc/hosts
    2. In the text editor (nano), scroll to the bottom of the file and add the following line:
    3. 185.199.108.133 raw.githubusercontent.com
    4. This tells your system that when it tries to access raw.githubusercontent.com, it should use the IP address 185.199.108.133.
    5. After adding the line, save the changes by pressing Ctrl + O (to write out) and then press Enter. To exit the text editor, press Ctrl + X.
    6. You've now added the entry to the /etc/hosts file. Try the installation again to see if it resolves the issue.

1. Output - CRUD Operations
