I wish I could boot the testnet network to get algod to work. So I created this Dockerfile:
FROM algorand/testnet:latest
USER root
ENV ALGORAND_DATA /root/node/data
ENV PATH /root/node:$PATH
RUN apt-get update && apt-get install wget -y && apt-get install curl -y
RUN cp ~/node/data/config.json.example ~/node/data/config.json \
&& sed -i '/\"Archival\"/c\\"Archival\": true,' ~/node/data/config.json \
&& sed -i '/\"EndpointAddress\"/c\\"EndpointAddress\": \"0.0.0.0:4001\",' ~/node/data/config.json \
&& sed -i '/\"IsIndexerActive\"/c\\"IsIndexerActive\": true,' ~/node/data/config.json
WORKDIR /root/node
ADD Entrypoint.sh /Entrypoint
RUN chmod +x /Entrypoint
ENTRYPOINT ["/Entrypoint"]
and the following Entrypoint.sh:
#!/bin/bash
goal node start
pgrep algod
goal node status -w 1000
To start it all I use the following commands:
docker build -t test-forum .
docker run test-forum
This is what I am shown after starting the Dockerfile:
But when I try to start this simple program:
from algosdk.v2client import algod
my_address = "YVNCNM6TEBWTLN6OO5UYSZZNPPOH2WOJBG3S6....."
algod_address = "http://localhost:4001"
algod_token = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
algod_client = algod.AlgodClient(algod_token, algod_address)
account_info = algod_client.account_info(my_address)
print("Account balance: {} microAlgos".format(account_info.get('amount')) + "\n")
I get this error:
