Algorand Follower node with docker

post by palakc on Jan 16, 2024

Hi Team,

I’m trying to setup an Algorand (Mainnet, Archival, Follower Node), as a prerequisite to setup Conduit and Indexer.

I’m using docker setup to start my node:

Image used: algorand/algod:latest

Command ran:

docker run --rm -it 
-p 4190:8080 
-p 4191:7833 
-e NETWORK=mainnet 
-e FAST_CATCHUP=1 
-e TELEMETRY_NAME=name 
-e TOKEN=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 
-e START_KMD=1 
-v ${PWD}/data:/algod/data/ 
--name mainnet-container 
algorand/algod:latest

This generates the folder structure, within which I see a config.json, where I have added enabled the required properties of follower node (EnableFollowMode, MaxAcctLookback, CatchupParallelBlocks).

I’m running into this error:

DNS LookupSRV failed when using system resolver: no signature in DNS response for _telemetry._tcp.default.algodev.network",
