Use go modules and go 1.14/1.15

[petderek]

Summary

Its 2020, time to update to go modules! We should update our build system to use the latest Go version available in AL2 as well.

Expected Behavior

I can update my dependencies and go build easily without installing a 3rd party dependency manager. 💪

Observed Behavior

I have to install a 3rd party dependency manager. ☹️

Environment Details

This should be tested:

• in travis
• in codebuild
• on a mac
• on a linux machine
• on/off amazon's corp

work in progress: #2493

[petderek]

1.15 was just released, meaning 1.13 is no longer supported.

Updated to Go 1.15 in #2660

I'm currently testing this:
in github action (in place of travis)
in codebuild
on a mac
on a linux machine
on/off amazon's corp

on a fresh ec2 instance I ran:

sudo yum -y install gcc git aws-cli wget rpm-build
GOVERSION="1.15"
GOLANG_TAR="go${GOVERSION}.linux-amd64.tar.gz"
wget -O /tmp/${GOLANG_TAR} https://storage.googleapis.com/golang/${GOLANG_TAR}
sudo tar -C /usr/local -xzf /tmp/${GOLANG_TAR}
mkdir -p ~/go/bin
mkdir -p ~/go/src

I added the following to my .bash_profile:

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT/bin:$GOBIN

then I ran:

source ~/.bash_profile
go get github.com/aws/amazon-ecs-agent && cd ~/go/src/github.com/aws/amazon-ecs-agent
go build -installsuffix cgo -a -ldflags ' -s' -o out/amazon-ecs-agent ./agent/

and a new agent was built.

I also tested on mac with the same golang setup -- downloaded go 1.15.7 (latest)

source ~/.bash_profile
go get github.com/aws/amazon-ecs-agent && cd ~/go/src/github.com/aws/amazon-ecs-agent
go build -installsuffix cgo -a -ldflags ' -s' -o out/amazon-ecs-agent ./agent/

also tested with codebuild and github actions.

note this is currently blocked by issues related to versioning as it relates to go modules.

Closing for now. This is not on our roadmap.
