Support Fabric v2.4.4 and later
Closed this issue · 4 comments
When I configure Fabric version as v2.4.4 in the configure file, I get following error:
Critical error occured:
- Json schema validation failed!
Errors found:
Schema validation:
- instance.global.fabricVersion : is not one of enum values: 1.3.0,1.4.0,1.4.1,1.4.2,1.4.3,1.4.4,1.4.5,1.4.6,1.4.7,1.4.8,1.4.9,1.4.10,1.4.11,1.4.12,2.0.1,2.1.0,2.1.1,2.2.0,2.2.1,2.2.2,2.2.3,2.2.4,2.3.0,2.3.1,2.3.2,2.3.3,2.4.0,2.4.1,2.4.2,2.4.3
It would be great if fablo can supports Fabric v2.4.4 and later versions, as the Golang chaincode with generic features can be packaged.
Thanks for pointing this out! We are working on an upgrade. Right now you can bypass validation for this case by adding a post-generate hook to Fablo config to replace it after network files are generated.
Assuming you have 2.4.3 version selected and you want to use 2.4.7, you can update your Fablo config as follows:
{
"global": {
"fabricVersion": "2.4.3",
...
},
...
"hooks": {
"postGenerate": "perl -i -pe 's/_VERSION=2.4.3/_VERSION=2.4.7/g' ./fablo-target/fabric-docker/.env"
}
}
Perl will replace Fabric version in relevant config file generated by Fablo. Also note that using perl instead of sed is a cross-platform solution, since sed has slightly different options on OSX and Linux.
I have been using this method successfully to update up to 2.4.9 and also updating fabric-ca to 1.5.6. I tried to update to 2.5.0 but get an error. This is the postgenerateHook I am using:
"postGenerate": "perl -i -pe 's/MaxMessageCount: 10/MaxMessageCount: 1/g' \"./fablo-target/fabric-config/configtx.yaml\"; perl -i -pe 's/_VERSION=2.4.3/_VERSION=2.5.0/g' ./fablo-target/fabric-docker/.env; perl -i -pe 's/FABRIC_CA_VERSION=1.5.0/FABRIC_CA_VERSION=1.5.6/g' ./fablo-target/fabric-docker/.env"

Is there a workaround available to get 2.5.0 working?
Fabric added back the go binary in version 2.5.1 so now I am able to start up the network with fablo.
