Streamr development environment

This repository contains Docker compose files and command line tool streamr_docker_dev for setting up a local Streamr development environment. The environment consists of Streamr services and supporting (3rd party) services. The data of the services is persisted on the local disk.

Setting up

OS X

Download, install, and run Docker Community Edition for Mac.
Increase the amount of memory allocated to Docker VM from 2GB to something like 5GB or more (Docker icon -> Preferences -> Advanced). Click Apply & Restart.
Clone this repo: git clone git@github.com:streamr-dev/streamr-docker-dev.git, change into that directory cd streamr-docker-dev
Create a symlink to streamr-docker-dev into a suitable directory in your PATH (run from repository root):

ln -sf $(pwd)/streamr-docker-dev/bin.sh /usr/local/bin/streamr-docker-dev

Linux

Install and start Docker service.
Clone this repo: git clone git@github.com:streamr-dev/streamr-docker-dev.git, change into that directory cd streamr-docker-dev
Add streamr-docker-dev into a suitable directory in your PATH (run from repository root), e.g.:

ln -sf $(pwd)/streamr-docker-dev/bin.sh /usr/local/bin/streamr-docker-dev

Windows

The docker stack has not been tested in a Windows environment and is not recommended at this time.

If you know what services you need, you don't need to use the bin.sh, you can just use docker-compose directly, like so:

Install and start Docker service.
Clone this repo: git clone git@github.com:streamr-dev/streamr-docker-dev.git, change into that directory cd streamr-docker-dev
Bind the loopback interface to 10.200.10.1: netsh int ip add address "Loopback" 10.200.10.1
For instance, for the Ethereum environment without core-api: docker-compose up parity-node0 parity-sidechain-node0 bridge

Quickstart

Option 1

streamr-docker-dev start --wait

Interacting with the local blockchain

The local Streamr Stack is configured to interact with the local Ethereum Parity node. Transactions should be near instant.

The recommended way to interact with the blockchain is through Metamask. Here is the network configuration to add:

Network Name: Streamr Local
RPC URL: http://localhost:8545 (mainchain) or http://localhost:8546 (sidechain)
ChainID: 8995 (mainchain) or 8997 (sidechain)

If you use StreamrClient, please configure MetaMask with the sidechain values.

Getting ETH on the local blockchain

There are pre-filled wallets with ETH & DATA on this chain to use.

Troubleshooting

Metamask can often get stuck when transacting on many different networks. A handy trick is to "Reset Account" in Settings/Advanced. This will remove the transaction history which helps it get unstuck.

`factory-reset`

"Factory reset" the docker environment by removing all images and persisted data: streamr-docker-dev factory-reset. Warning: this will delete all your docker images and their state, not just ones related to the Streamr stack.

Accessing the Core app and Streamr API

Once the services are running, browse to http://localhost to use Core.

The API root is at http://localhost/api/v2.

Usage in Streamr development

When you're developing one of the Streamr components, you'll want to use the streamr-docker-dev tool with the --except flag to exclude the service you're developing:

streamr-docker-dev start --except [service-under-development]

Usage in testing and CI

In CI, the --wait flag can be used with start to block until all health checks are passing. This ensures that the services are up and running before starting your tests.

For integration tests, use the --except option to exclude the service under test:

streamr-docker-dev start --except [service-under-test] --wait

When testing the SDKs or running other end-to-end tests, just start the full stack before your tests:

streamr-docker-dev start --wait

1 x ipfs for TheGraph
1 x adapter for ENS queries from sidechain to mainchain

Troubleshooting

Metamask transactions are stuck

This is a common problem on Metamask when switching inbetween chains. Clearing the transaction history in Metamask usually fixes this issue: Click, 'Settings', then 'Advanced', then, 'Reset Account'.

Making image uploads to AWS work

Uploading images to AWS needs credentials to be able to access the target S3 bucket.

copy .env.example as .env and change the values to correct ones (Note: .env file is in .gitignore)
Restart engine-and-editor and S3 services should work. You can debug any potential issues with streamr-docker-dev log -f engine-and-editor.

Error response from daemon

Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

This is a connection issue; could be DNS settings, could be firewall. For me, changing to another wlan helped.

I received this error only during docker login, after login I could resume using office wlan (docker pull works somehow differently).
