Problems with tutorial

[mathiskruger]

The tutorial doesn't directly state that Docker is a pre-requisite to continue the tutorial. Neither does it state how to install it.

Regarding more important issues:

The daemon must be started prior to execute the docker run command (otherwise there are error messages shown). The error that is shown is "docker:cannot connect to the docker daemon. Is the docker daemon running on this host?". I tried multiple commands and the command that only seems to work is "sudo dockerd" I don't know if this is normal as it's not stated in the tutorial. I then had to put sudo in every command that I placed.

Many errors and warnings flashed up when launching logisland (I don't know what I did, I'm still a noob XD). Personally I think a marker should be placed in the tutorial to differentiate between a command and a sample, then again I don't have experience so you can take my word lightly.

Then again other errors were shown such as : WARN VerifiableProperties:83 - Property retry.backoff.ms is not valid and errors with injecting data access logs : None of the configured nodes were available: [{Sprite}{8E5SgjqaQ5eEaCo2VZ-Dsg}{172.17.0.2}{sandbox/172.17.0.2:9300}]
and later...
PutElasticsearch:187 - done bulk request in 22351 ms with failure = true

Well fingers crossed, lets hope I discovered a new branch of computer science with all these errors. Might be my fault or the systems but I think it's worth to take a look :)!
