I cant seem to get the latest version of Geth 1.8.3 working. It stops and never starts syncing.

I'm trying to get it on to the rinkeby.io testnet for smart contract testing.

I had success with 1.7.3 after downloading and using ADD to copy the files to the image. But I would like to automate the build, so that it can be used in Google cloud with a deployment.yml.

Currently I'm testing on my local machine since I know the firewall worked with 1.7.3. (no specific rules set)

The Dockerfile builds just fine and I can see that it shows up in the rinkeby.io node list, but even after 1 hour not a single block has been synced. its stuck on: IPC endpoint opened

With 1.7.3 it took 10-15 seconds to start the sync.

Dockerfile

I did find out what was wrong after rebuilding the Dockerfile from scratch. At the end of my CMD line there is this ending.

?discport=30304

By removing it, it works as intended.

This was a remnant from a different users code.

For me the problem is the fast sync still running for hours, takes forever and never stops on its own.

I ran this command : **geth --rinkeby --syncmode "fast" --rpc --rpcapi db,eth,net,web3,personal --cache=1024 --rpcport 8545 --rpcaddr 127.0.0.1 --rpccorsdomain "*" **

consuming storage as it´s still running(over 5GB), sometimes I got an error : No space left on device, I deleted everything and then start over.

I run eth.syncing , here´s what I got:

https://i.stack.imgur.com/uasFl.jpg ( after 3 hours of sync )

https://i.stack.imgur.com/wEBWW.jpg ( 30 min after the first eth.syning check )

I tried 100 * eth.syncing.currentBlock / eth.syncing.highestBlock and I got 99.9969.... and then it keeps slowing down and decreasing and never reached 99.9970.

I am running Geth/v1.8.4-stable-2423ae01/linux-amd64/go1.10 on Ubuntu 16.04LTS

After going round and round, I discovered that using the '--bootnodes' flag is the simplest way to get your private peers to recognize each other across a network:

Geth.exe --bootnodes "enode://A@B:30303" --datadir="C:\Ledger"--nat=extip:192.168.0.9 ...

When spinning up your IPC pipe, specify a node that is likely to always be up (likely your first init'd node). You also need to be very explicit about IP addresses using the '--nat' flag. In the above example A is the IP address of the node that will be used to auto-detect all other nodes, and build peer connections.

I dervied this approach using information found in this link on the Geth Github site.
