I'm a CS major who wants to learn EOS dapp development, but I'm still very much a beginner. On my native Ubuntu machine, I ran
sudo docker network create eosnetwork
after the previous steps in the documentation (https://www.eosdocs.io/dappdevelopment/software/docker) and then
sudo docker run --name server --network=eosnetwork --rm -p 7777:7777 -i eosio/eos /bin/bash -c "nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --http-server-address=0.0.0.0:7777 --access-control-allow-origin=* --http-validate-host=0"
and they don't return to prompt after several minutes. Do I have to keep waiting? I hit ctrl-c and now if I run the first one again, it says Error response from daemon: network with name eosnetwork already exists. Do I have to simply wait more? How do I try it again?
Edit: I think those docs are outdated so I was referred to https://developers.eos.io/eosio-home/docs, and I think I successfully followed section 1.3, but in 1.4 I don't have enough physical memory to install CDT. What can I do?
