When you create an initContainer and execute this command:

command: ['sh', '-c', 'tar -xvf /hlf/channel-artifacts/channel-artifacts.tar']

it runs in default for this container path. I checked this by adding pwd and ls -l commands.

Whole line is:

command: ['sh', '-c', 'tar -xvf /hlf/channel-artifacts/channel-artifacts.tar ; pwd ; ls -l']

From an initContainer you can get logs by:

kubectl logs fabric-orderer-01-xxxxxx -c init-channel-artifacts

Answered 2021-Mar-31 at 07:13

according to your describe,in the tourial ,fabric version is v1.4.X,and the fabric you now use is v2.x.x,so in v1.4.x the test script is byfn.sh and in v2.x.x the test script is network.sh,these two scripts are different.

if you want to backup a fabric network and restore,you need just backup crypto-config(organizations in v2.x.x),ledger data which obtain from /var/hyperledger/fabric of docker container,and start your orderer and peer container ,you need not create channel or join channel ,you can query and invoke chaincode.

I have answer another question about restore fabric network,you can reference it In Hyperledger Fabric, is there a way to reuse the data of previous network?

--------------new answer-------------------------------

if you exec you peer chaincode invoke command in terminal,you should add this env,and you can invoke success.

I have a helm chart and I need to create a file before installing all my resources to be able to store it in a secret. I have been reading about Helm Hooks and I think I can create a hook, insert my script files, run my script and generate the file I need, where I'm lost is on how can I get my file out of the pod and insert it as a secret.

These are my hooks:

I recommend going over https://github.com/helm/charts/tree/master/stable and https://github.com/bitnami/charts to reuse existing solution

Helm Template https://github.com/bitnami/charts/blob/master/bitnami/rabbitmq/templates/secrets.yaml uses randAlphaNum template function https://helm.sh/docs/chart_template_guide/function_list/#randalphanum-randalpha-randnumeric-and-randascii to generate the secret.

The problem with randAlphaNum generating new secret every time helm install/upgrade command is run is solved by https://github.com/helm/helm/issues/3053#issuecomment-782837107 using lookup template function https://helm.sh/docs/chart_template_guide/functions_and_pipelines/#using-the-lookup-function.

I have a problem switching from levelDB to couchDB as the state database. I'm using the test-network from the hyperledger sample repository and I have edited the docker-compose-couch.yaml file inside of the docker folder and the core.yaml file inside of the config folder.
These are all the changes that I made, but when I start the network it still uses leveldb.

QUESTION

std::algorithm to make this more expressive

Asked 2020-Nov-26 at 18:03

I'm working on my own blockchain implementation in C++17.

To learn as much as possible, I would like to reduce loops as least as possible, moving to the alternative (and more expressive) loops within the std::algorithm library.

In a nullshell, within the Blockchain algorithm, each block contains it's own hash and the hash of the previous block (except the Genesis-Block which doesn't contain a previous block [first in the container]).

I want to implement a Validate function in the Blockchain object that takes pairs of blocks (which are contained in a std::vector), and checks the hashes (and previous hashes) to make sure they haven't been tampered with.

Current code (works):

If you have some range v where you want to check each adjacent element for some condition, and return early, you can use std::adjacent_find.

First write a lambda that compares adjacent elements:
