MEV-BOOST:无法连接到Builder

Question

我正在尝试在goerli测试网上尝试使用mev，但是我在我的信标节点日志中得到了连接错误。

MEV助推指令：

sudo docker run flashbots/mev-boost -goerli  -relay-check -relays=https://0xafa4c6985aa049fb79dd37010438cfebeb0f2bd42b115b89dd678dab0670c1de38da0c4e9138c9290a398ecd9a0b3110@builder-relay-goerli.flashbots.net

这是我的日志：

time="2022-09-16T10:29:58Z" level=info msg="listening on localhost:18550" module=cli

很明显，mev客户端正在本地主机上运行:18550。

这是我在Goreli-Prater测试网上的灯塔节点命令。

docker run -d -it -v /home/lucy/launch/prysm:/root -v /home/lucy/launch/geth/genesis.ssz:/genesis.ssz -v /home/lucy/launch/jwt.hex:/jwt.hex -p 4000:4000 -p 13000:13000 -p 12000:12000/udp --name beacon --net=host gcr.io/prysmaticlabs/prysm/beacon-chain:stable --datadir=/root --genesis-state=/genesis.ssz --accept-terms-of-use=true --rpc-host=0.0.0.0 --monitoring-host=0.0.0.0 --execution-endpoint=http://localhost:8551 --jwt-secret=/jwt.hex --suggested-fee-recipient=0x7Db8bD7FF6a856c1715a58BB4fd83BF43519bDa3 --http-mev-relay=http://localhost:18550  --prater

以下是运行上述信标节点命令后的错误日志

我在mev客户端或信标节点上没有任何命令吗？为什么我的信标节点不能连接到mev客户端？这是码头连接问题吗？

救命啊！！

Answer 1

您可能需要调整网络如何在您的各个独立的码头集装箱工作。这里的这条线告诉我们，您的信标节点无法到达您的mev过程：

[2022-09-16 10:34:38] ERROR main: could not connect to builder: Get "http://localhost:18550/eth/v1/builder/status": dial tcp 127.0.0.1:18550: connect: connection refused

默认情况下，启动码头独立容器时将使用网桥驱动程序。如果您启动您的mev独立集装箱，像您现在正在做的，它将生活在它自己的孤立的网络岛。要解决这个问题，您可能需要使用主机联网启动它。

这意味着启动mev-助推器的方式如下：

sudo docker run --network host flashbots/mev-boost -goerli  -relay-check -relays=https://0xafa4c6985aa049fb79dd37010438cfebeb0f2bd42b115b89dd678dab0670c1de38da0c4e9138c9290a398ecd9a0b3110@builder-relay-goerli.flashbots.net
