Building CentOS AMI

Prerequire

CentOS7 - AMI build script only works on CentOS7.

AMI variables

Create dist/ami/variables.json with following format, specify AMI variables:

{
    "access_key": "xxx",
    "secret_key": "xxx",
    "subnet_id": "subnet-xxx",
    "security_group_id": "sg-xxx",
    "region": "us-east-1",
    "associate_public_ip_address": "true",
    "instance_type": "c4.xlarge",
    "ami_prefix": "YOUR_NAME-"
}

You can use dist/ami/variables.json.example as template.

Build AMI from locally built rpm

If you want to make AMI with modified scylla source code, this is what you want. Please be sure everything is committed, RPM build script drops uncommitted files.

To build AMI from locally built rpm, run

./dist/ami/build_ami.sh --localrpm

Since build script skips building rpm when it's already exists on dist/ami/files/, please rm dist/ami/files/scylla-server.x86_64.rpm when you want to build AMI with new rpm.

Build AMI from yum repository

To build AMI from unstable yum repository, run

./dist/ami/build_ami.sh --repo http://downloads.scylladb.com.s3.amazonaws.com/rpm/unstable/centos/master/latest/scylla.repo

To build AMI from release yum repository, run

./dist/ami/build_ami.sh

git checkout -b branch-1.5 remotes/origin/branch-1.5

## init the submoudles
git submodule init
