I want to execute a performance evaluation test on a deployed Hyperledger Composer business network using Hyperledger Caliper.
Into the official documentation there is a section for the Composer configuration but I think that it's not very user friendly for those approaching this framework for the first time and I cannot find a better basic step-by-step tutorial for configuring and running an evaluation test.
Check that all the prerequisites are installed:
NodeJS 8 (LTS), 9, or 10 (LTS) higher versions are not supported as
the dependancy chain does not permit this
node-gyp
Docker
Docker-compose
Build Caliper:
Run npm install in Caliper root folder to install base dependencies locally
Run npm run repoclean in Caliper root folder to ensure that all the packages are clean
Run npm run bootstrap to bootstrap the packages in the Caliper repository. This will install all package dependancies and link any cross dependancies. It will take some time to finish installation. If it is interrupted by ctrl+c, please recover the file package.json first and then run npm run bootstrap again.
Do not run any of the above commands with sudo, as it will cause the bootstrap process to fail
Install the Caliper CLI
Execute the following command from the packages/caliper-tests-integration directory:
npm run e2e_install
Run a Sample Benchmark
from caliper/packages/caliper-samples/ run
caliper benchmark run -c benchmark/composer/config.yaml -n network/fabric-v1.3/2org1peercouchdb/composer.json -w ../caliper-samples/
where the parameters means:
-w : path to a workspace directory (required)
-c : relative path from the workspace to the benchmark configuration file (required).
-n : relative path from the workspace to the config file of the blockchain network under test (required).
To create tests for your Business Network you need to modify the config.yaml and composer.json files. You also have to create a .js file where you need to implement the test to be runned, and specify the path to this file in the callback section of config.yaml file.

I use vuetify (vue)
Is it mandatory for each deployment to production for remove node modules and run npm install? Or just run npm run build?
I have two option :
Option 1 : Every deployment, I run the npm run build directly
Option 2 :
Delete the contents of dist folder
Delete node_modules folder
npm install
npm run build
Which is the best option?
npm install
This command installs a package, and any packages that it depends on. If the package has a package-lock or shrinkwrap file, the installation of dependencies will be driven by that, with an npm-shrinkwrap.json taking precedence if both files exist. See package-lock.json and npm-shrinkwrap.
If you did not install or update the package before releasing the project, you do not need to execute npm install, otherwise, you need to execute it to ensure that dependent packages on the production environment is consistent with your local dependent package version.
If you are using an automatic build deployment tool like jenkins, for convenience you can execute the install command before each build. It's okay.
Imagine more environments, not just a production:
development
testing1
staging
uat
production
Can we upload the npm run build result (compressed js) or node_modules to our git repository? ANSWER IS NOT!!. So if you need to have a version of your app running in any of these environments, you must to execute npm run build. And this command needs the classic npm run install. I think this last sentence, answer your question.
(ADVICE) Docker to the rescue
assumption 1 your client-side app (vue) is not complex(no login, no session, no logout, etc ), you could publish it using a basic nginx, apache, basic-nodejs.
assumption 2 you are able to have one more server for docker private repository. Also if you are in google, amazon o azure, this service is ready to use, of course a payment is required
In one line, with docker you must execute just one time npm install and npm run build. Complete flow is:
developer push some changes to the git repository
manually or automatically a docker build in launched.
inside Dockerfile, npm install and npm run build is executed. Also a minimal server with nodejs (example) is configured pointing to your builded assets
your new docker image is uploaded to your docker private repository
that's all
If your quality assurance team needs to perform some tests to your new app, just a docker image download is required. If everything is ok, you pass to the next stage (staging or uat) or production. Steps will be the same: just download the docker image.
Optimizations
Use docker stages to split build and start steps
If your app does not have complex flows(no login, no session, no logout, etc ), replace node basic server with a simple nginx
I need login and logout
In this case, nginx or apache does not helps you because they are a simple static servers.
You could use a minimal nodejs code like this:
https://github.com/jrichardsz/nodejs-static-pages/blob/master/server.js
Adding /login , /logout, etc
Or use my server:
https://github.com/utec/geofrontend-server
which has a /login, /logout and other cool features for example: How are you planning to pass your backend api urls to your vue app in any of your environments?.
It's a kind of not normal thing, but this is something, that temporarily is a solution.
I have laradock installed in a system and laravel app.
All that I'm using from laradock provides me command below
docker-compose up -d nginx mysql php-worker workspace redis
I need to add node package (https://www.npmjs.com/package/tiktok-scraper) installed globally in my docker, so I can get results by executing php code like below
exec('tiktok-scraper user username-n 3 -t json');
This needs to be available for php-fpm and php-worker level, as I need this in jobs and for endpoints, that should invoke scrape.
I know, that I'm doing wrong, but I have tried to install it within workspace like using
docker-compose exec workspace bash
npm i -g tiktok-scraper
and after this it's available in my workspace (I can run for instance tiktok-scraper --help) and it will show me the different options.
But this doesn't solve the issue, as I'm getting nothing by exec('tiktok-scraper user username-n 3 -t json'); in my laravel app.
I'm not so familiar with docker and not sure, in which dockerfile should I put something like
RUN npm i -g tiktok-scraper
Any help will be appreciated
Thanks
To execute the npm package from inside your php-worker you would need to install it in the php-worker container. But for the php exec() to have an effect on your workspace this workspace would need to be in the same container as your php-worker.
I have a Jenkins server on which I observe a private git repository for changes, which then triggers a pipeline script (the repository contains a nodejs app). In this pipeline script I need to do the following steps:
Install dependencies (npm install)
Build my application (npm run build, which creates a dist folder)
Build a docker container (docker build) and run the container (which runs a script in the dist folder)
Which of the following two options would be the recommended way to do this, and why?
Option A: Run npm install and npm run build in the jenkins pipeline and copy the dist folder to the docker container during the docker build. This would allow me to only install runtime dependencies in the docker container using npm install --only=production, therefore reducing the image size significantly.
Option B: Run npm install and npm run build during docker build (In the Dockerfile). This would allow me to run the docker container outside the CI server if I have to (I don't have a use case for it now, but it seems cleaner because it is more independent). However, the image size would significantly increase and I am not sure if this is the recommended way.
Any suggestions?
I would choose option B.
The reason behind it would be that there are some npm packages that runs a node-gyp, gcc, and other platform-dependent builds.
Look at the popular bcrypt package as an example.
Going with option A would mean that your docker and Jenkins machine need to hold the same infra for such builds which is not common, to say the least.
I am facing some issues with my network proxy, so I am trying hit and trial sort of approach to try different proxies. I need to give the proxy configuration during composer network install command within npmConfig file, now once I have given one proxy, how can I change it, as I cannot use composer network install again for same business network.
The npmrcFile option is available on the composer network install command and once the install is done - the npmrcFile is bundled with that install package on the peers.
Because you cannot build a chaincode container due to proxy issues (ie your issues stated), start will not be successful and so thus you cannot use composer network upgrade with -o <options> to upgrade the business network with new npmrcFile changes via 'options'. This is why its best to try it out your proxy configs in a simple Dev Fabric environment - you can blow away the peer each time and install a new Fabric - once it is working (its a one-off task), then you have the correct npmrcFile to install as appropriate etc.
If need be you could use wget http://npmregistry:4873/ from a test docker container (where you do a test npm install) to see if you can connect via your network proxy - then once you know, your config file should be read when it (re-)tries the docker build.
Hope this helps.
I am trying to use this sample to demonstrate the chatbot testing using node "testmybot" package. When I execute "npm install" command I am getting error. Please find the screenshot of the same attached below.
Steps that I have followed:
1. Downloaded the project from [https://github.com/codeforequity-at/testmybot-sample-calculator]
2. Extracted the project to "testmybot-sample-calculator-master" folder
3. Inside the folder executed "npm install" command
4. After installing some packages, looks like while installing botkit package it is throwing error
Please let me know if I have missed out any steps.
To run this sample, there is now a Dockerfile included in the Github repository. The following commands should retrieve the latest files from Github, build a docker container and running the sample test cases inside.
$ git pull
$ docker build -t testmybot-sample-calculator .
$ docker run testmybot-sample-calculator
Obviously, you have to install docker first.
UPDATE:
I was able to reproduce it on a Windows workstation, user had no admin rights. Found solution here: you have to install the windows-build-tools package first, with a user having admin rights:
npm install --global --production windows-build-tools
Afterwards, installation of the package in question was possible.
