# Roadworker
__Note:__ This software is just transferred from https://github.com/codenize-tools (maintained by [@winebarrel](https://github.com/winebarrel]) which was archived. [Cookpad](https://github.com/cookpad) and [@sorah](https://github.com/sorah) asked @winebarrel for inheriting this project and took its ownership as a new maintainer.
Roadworker is a tool to manage Route53.
It defines the state of Route53 using DSL, and updates Route53 according to DSL.

## Routefile example
```ruby
require 'other/routefile'
hosted_zone "winebarrel.jp." do
rrset "winebarrel.jp.", "A" do
ttl 300
resource_records(
"127.0.0.1",
"127.0.0.2"
)
end
rrset "winebarrel.jp.", "MX" do
ttl 300
resource_records(
"10 mx.winebarrel.jp",
"10 mx2.winebarrel.jp"
)
end
end
hosted_zone "info.winebarrel.jp." do
rrset "xxx.info.winebarrel.jp.", "A" do
dns_name "elb-dns-name.elb.amazonaws.com"
end
rrset "yyy.info.winebarrel.jp.", "A" do
dns_name "elb-dns-name2.elb.amazonaws.com", :evaluate_target_health => true
end
rrset "zzz.info.winebarrel.jp", "A" do
set_identifier "Primary"
failover "PRIMARY"
health_check "http://example.com:80/path", :search_string => "ANY_RESPONSE_STRING", :request_interval => 30, :failure_threshold => 3
# If you want to specify the IP address:
#health_check "http://192.0.43.10:80/path", :host => "example.com",...
ttl 456
resource_records(
"127.0.0.1",
"127.0.0.2"
)
end
rrset "zzz.info.winebarrel.jp", "A" do
set_identifier "Secondary"
failover "SECONDARY"
health_check "tcp://192.0.43.10:3306", :request_interval => 30, :failure_threshold => 3
ttl 456
resource_records(
"127.0.0.3",
"127.0.0.4"
)
end
end
# Private HostedZone
hosted_zone "winebarrel.local." do
vpc "us-east-1", "vpc-xxxxxxxx"
vpc "us-east-2", "vpc-xxxxxxxx"
rrset "winebarrel.local.", "A" do
ttl 300
resource_records(
"10.0.0.1",
"10.0.0.2"
)
end
end
```
### Calculated Health Checks
```ruby
rrset "zzz.info.winebarrel.jp", "A" do
set_identifier "Secondary"
failover "SECONDARY"
health_check :calculated => ["07c03a45-5b69-4044-9ec3-016cd8e5f74b", "bba4d1ea-27c2-4d0c-a249-c857a3e46d88"], :health_threshold => 1, :inverted => false
ttl 456
resource_records(
"127.0.0.3",
"127.0.0.4"
)
end
```
### Cloudwatch Metric Health Checks
```ruby
rrset "zzz.info.winebarrel.jp", "A" do
set_identifier "Secondary"
failover "SECONDARY"
health_check :cloudwatch_metric => {:region=>"ap-northeast-1", :name=>"MyCheck"}, :inverted => false, :insufficient_data_health_status => "LastKnownStatus"
ttl 456
resource_records(
"127.0.0.3",
"127.0.0.4"
)
end
```
### Dynamic private DNS example
```ruby
require 'aws-sdk'
hosted_zone "us-east-1.my.local." do
vpc "us-east-1", "vpc-xxxxxxxx"
resp = Aws::EC2::Client.new(region: "us-east-1").describe_instances(filters:[{ name: 'vpc-id', values: ["vpc-xxxxxxxx"] }])
instances = resp.reservations.each_with_object({}) do |reservation, reservations|
reservations.merge!(reservation.instances.each_with_object({}) do |instance, instances|
tag_name = instance.tags.find {|tag| tag['key'] == 'Name' }
instances[instance.private_ip_address] = tag_name['value'] if tag_name and tag_name['value'] != ''
end)
end
instances.each {|private_ip_address, tag_name|
rrset "#{tag_name}.us-east-1.my.local.", "A" do
ttl 300
resource_records private_ip_address
end
}
end
```
### Use template
```ruby
template "default_rrset" do
rrset context.name + "." + context.hosted_zone_name, "A" do
ttl context.ttl
resource_records(
"127.0.0.1"
)
end
end
hosted_zone "winebarrel.jp." do
context.ttl = 100
include_template "default_rrset", :name => "www"
include_template "default_rrset", :name => "www2"
end
```
### Exclude specific records from management under Roadworker
Use this if your zone contains rrsets managed by other tools, and you want to ignore them in Roadworker.
```ruby
hosted_zone "winebarrel.jp." do
ignore "ignore.winebarrel.jp"
ignore /^regexp-ignore/
# *.ignore2.winebarrel.jp and ignore2.winebarrel.jp
ignore_under "ignore2.winebarrel.jp"
end
```
## Test
Routefile compares the results of a query to the DNS and DSL in the test mode.
```
shell> roadwork -t
..F..
info.winebarrel.jp. A:
expected=127.0.0.1(300),127.0.0.3(300)
actual=127.0.0.1(300),127.0.0.2(300)
5 examples, 1 failure
```
(Please note test of A(Alias) is not possible to perfection...)
