unable to install Chaos Monkey

[ruturaj kalyani]

Hi,

I am trying to install chaos monkey referring https://github.com/Netflix/chaosmonkey/wiki/How-to-deploy 

I have setup Spinnaker and MySQL on AWS_EC2 instance.

when I run "go install github.com/netflix/chaosmonkey/bin/chaosmonkey" I am getting below error.

 $go install github.com/netflix/chaosmonkey/bin/chaosmonkey
can't load package: package github.com/netflix/chaosmonkey/bin/chaosmonkey: cannot find package "github.com/netflix/chaosmonkey/bin/chaosmonkey" in any of:
        /usr/local/go/src/pkg/github.com/netflix/chaosmonkey/bin/chaosmonkey (from $GOROOT)
        /usr/local/sbin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey (from $GOPATH)
        /usr/local/bin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/sbin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/bin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /sbin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /bin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/games/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/local/games/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/local/go/bin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey
        /usr/local/go/bin/src/github.com/netflix/chaosmonkey/bin/chaosmonkey

can anyone tell what the issue is?

Hi,

"go install" won't download dependencies, AFAIK. Try "go get" instead.

hi Mathias,

I executed "sudo go get github.com/netflix/chaosmonkey/bin/chaosmonkey" and got below error:

error: "package github.com/netflix/chaosmonkey/bin/chaosmonkey: cannot download, $GOPATH not set. For more details see: go help gopath"

go path is also set. any idea??

go env
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/go/bin:/usr/local/go/bin:/usr/local/go/bin"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/lib/gccgo/tool"
TERM="dumb"

As the error says, you need to set the $GOPATH environment variable.

Also check that $GOPATH is part of $PATH, so that the chaosmonkey executable can be found after installing it.

This is my personal setup from my .bashrc:

export GOPATH="$HOME/devel/go"
export GOROOT="$(go env GOROOT)"
export PATH="$GOPATH/bin:$GOROOT/bin:$PATH"

Afterward, this should work:

$ go get github.com/netflix/chaosmonkey/bin/chaosmonkey
$ chaosmonkey --version
2.0.2

Chaos Monkey versions all its dependencies, so there *shouldn't* be a need to download other dependencies.

executed  :

$ go get github.com/netflix/chaosmonkey/bin/chaosmonkey

      and then :

$ chaosmonkey --vesion

however, no version returned. got error "chaosmonkey bad command".

which is the best/easiest way to install chaos monkey? 

[Mathias Lafeldt]

Lorin,

"go install" won't download anything, be it internal (vendored) or external dependencies. That's the reason why it's not the right command to install chaosmonkey from scratch (without the source code already checked out).

Try it yourself. This won't work:

$ GOPATH=/tmp/go

$ go install github.com/netflix/chaosmonkey/bin/chaosmonkey

"go get" will also download the source code, allowing people to install chaosmonkey with a single command.

While at it, there's also a standard name for the folder where commands live in. It's called "cmd". So the path should be github.com/netflix/chaosmonkey/cmd/chaosmonkey. Given that the project is primarily a command-line tool, you could even move the main function to the root so that installing becomes as easy as "go get github.com/netflix/chaosmonkey".

Thanks, Mathias. I'll update the readme and wiki accordingly. (I have on my todo list to switch to something like mkdocs for docs so others can submit PRs.

As far using the cmd directory convention, would you be willing to submit a PR for this?

In this case, I did not put the main function in the root because we consume this code internally at Netflix as a library in order to create a binary with some Netflix-specific code.

Hi Ruturaj:

I think you had a typo in the flag: "--ve[r]sion" (the r was missing).

Take care,

Lorin

Hello Lorin,

executed the command again, still getting "chaosmonkey: command not found". see below:

ubuntu@ip-x-x-x-xx:/usr/local/go/bin/bin$ chaosmonkey --version
chaosmonkey: command not found
ubuntu@ip-x-x-x-xx:/usr/local/go/bin/bin$

Hi Ruturaj:

My guess is the "command not found" message you are getting is coming from your shell not being able to find the "chaosmonkey" binary in your PATH environment variable. Can you try doing:

"which chaosmonkey"

Also, try this from the directory that contains the binary:

./chaosmonkey --version
