jekyll-s3
[] (http://travis-ci.org/laurilehmijoki/jekyll-s3)
Deploy your jekyll site to S3.
What jekyll-s3 can do for you
- Upload your site to AWS S3
- Help you use AWS Cloudfront to distribute your Jekyll blog
- Create an S3 website for you
- Improve page speed with HTTP cache control and gzipping
- Set HTTP redirects for your website
- (for other features, see the documentation below)
Install
gem install jekyll-s3
Usage
- Go to your jekyll site directory
- Run
jekyll-s3
. It generates a configuration file called _jekyll_s3.yml
that looks like this:
s3_id: YOUR_AWS_S3_ACCESS_KEY_ID
s3_secret: YOUR_AWS_S3_SECRET_ACCESS_KEY
s3_bucket: your.blog.bucket.com
-
Edit it with your details (you can use ERB in the file)
-
Run configure-s3-website --config-file _jekyll_s3.yml
This will configure
your bucket to function as an S3 website. If the bucket does not exist,
configure-s3-website
will create it for you.
-
Run jekyll-s3
to push your Jekyll blog to S3. Congratulations! You are live.
(If you are using jekyll-s3
on an EC2 instance with IAM
roles,
you can omit the s3_id
and s3_secret
keys in the config file.)
Using environment variables
You can use ERB in your _jekyll_s3.yml
file which incorporates environment variables:
s3_id: <%= ENV['S3_ID'] %>
s3_secret: <%= ENV['S3_SECRET'] %>
s3_bucket: blog.example.com
Additional features
Cache Control
You can use the max_age
configuration option to enable more effective browser
caching of your static assets. There are two possible ways to use the option:
you can specify a single age (in seconds) like so:
max_age: 300
Or you can specify a hash of globs, and all files matching those globs will have
the specified age:
max_age:
"assets/*": 6000
"*": 300
Place the configuration into the file _jekyll_s3.yml
.
Gzip Compression
If you choose, you can use compress certain file types before uploading them to
S3. This is a recommended practice for maximizing page speed and minimizing
bandwidth usage.
To enable Gzip compression, simply add a gzip
option to your _jekyll_s3.yml
configuration file:
gzip: true
Note that you can additionally specify the file extensions you want to Gzip
(.html
, .css
, .js
, and .txt
will be compressed when gzip: true
):
gzip:
- .html
- .css
- .md
Remember that the extensions here are referring to the compiled extensions,
not the pre-processed extensions.
Using non-standard AWS regions
By default, jekyll-s3
uses the US Standard Region. You can upload your Jekyll
site to other regions by adding the setting s3_endpoint
into the
_jekyll_s3.yml
file.
For example, the following line in _jekyll_s3.yml
will instruct jekyll_s3
to
push your site into the Tokyo region:
s3_endpoint: ap-northeast-1
The valid s3_endpoint
values consist of the S3 location constraint
values.
Ignoring files you want to keep on AWS
Sometimes there are files or directories you want to keep on S3, but not on
your local machine. You may define a regular expression to ignore files like so:
ignore_on_server: that_folder_of_stuff_i_dont_keep_locally
Reduced Redundancy
You can reduce the cost of hosting your blog on S3 by using Reduced Redundancy Storage:
- In
_jekyll_s3.yml
, set s3_reduced_redundancy: true
- All objects uploaded after this change will use the Reduced Redundancy Storage.
- If you want to change all of the files in the bucket, you can change them through the AWS console, or update the timestamp on the files before running
jekyll-s3
again
How to use Cloudfront to deliver your blog
It is easy to deliver your S3-based web site via Cloudfront, the CDN of Amazon.
Creating a new CloudFront distribution
When you run the command configure-s3-website
, it will ask you whether you
want to deliver your website via CloudFront. If you answer yes,
configure-s3-website
will create a CloudFront distribution for you.
This feature was added into the version 1.3.0 of the configure-s3-website
gem.
For more information, see the gem's
documentation.
Using your existing CloudFront distribution
If you already have a CloudFront distribution that serves data from your Jekyll
S3 bucket, just add the following line into the file _jekyll_s3.yml
:
cloudfront_distribution_id: your-dist-id
Next time you run jekyll-s3
, it will invalidate the items on CloudFront and
thus force the CDN system to reload the changes from your Jekyll S3 bucket.
Specifying custom settings for your CloudFront distribution
The gem configure-s3-website
, which is a dependency of jekyll-s3
, lets you
define custom settings for your CloudFront distribution.
For example, like this you can define a your own TTL and CNAME:
cloudfront_distribution_config:
default_cache_behavior:
min_TTL: <%= 60 * 60 * 24 %>
aliases:
quantity: 1
items:
CNAME: your.website.com
See the gem's
documentation for more
info.
The headless mode
Jekyll-s3 has a headless mode, where human interactions are disabled.
In the headless mode, jekyll-s3
will automatically delete the files on the S3
bucket that are not on your local computer.
Enable the headless mode by adding the --headless
or -h
argument after
jekyll-s3
.
Configuring redirects on your Jekyll S3 website
You can set HTTP redirects on your Jekyll S3 website in two ways. If you only
need simple "301 Moved Premanently" redirects for certain keys, use the
Simple Redirects method. Otherwise, use the Routing Rules method.
Simple Redirects
For simple redirects Jekyll S3 uses Amazon S3's
x-amz-website-redirect-location
metadata. It will create zero-byte objects for each path you want
redirected with the appropriate x-amz-website-redirect-location
value.
For setting up simple redirect rules, simply list each path and target
as key-value pairs under the redirects
configuration option:
redirects:
index.php: /
about.php: about.html
music-files/promo.mp4: http://www.youtube.com/watch?v=dQw4w9WgXcQ
Routing Rules
You can configure more complex redirect rules by adding the following
configuration into the _jekyll_s3.yml
file:
routing_rules:
- condition:
key_prefix_equals: blog/some_path
redirect:
host_name: blog.example.com
replace_key_prefix_with: some_new_path/
http_redirect_code: 301
After adding the configuration, run the command configure-s3-website --config _jekyll_s3.yml
on your command-line interface. This will apply the routing
rules on your S3 bucket.
For more information on configuring redirects, see the documentation of the
configure-s3-website
gem, which comes as a transitive dependency of the jekyll-s3
gem.
Using jekyll-s3
as a library
By nature, jekyll-s3
is a command-line interface tool. You can, however, use
it programmatically by calling the same API as the executable jekyll-s3
does:
require 'jekyll-s3'
is_headless = true
Jekyll::S3::CLI.new.run('/path/to/your/jekyll-site/_site/', is_headless)
You can also use a basic Hash
instead of a _jekyll_s3.yml
file:
config = {
"s3_id" => YOUR_AWS_S3_ACCESS_KEY_ID,
"s3_secret" => YOUR_AWS_S3_SECRET_ACCESS_KEY,
"s3_bucket" => "your.blog.bucket.com"
}
in_headless = true
Jekyll::S3::Uploader.run('/path/to/your/jekyll-site/_site/', config, in_headless)
The code above will assume that you have the _jekyll_s3.yml
in the directory
/path/to/your/jekyll-site
.

reference, you can look at the existing Jekyll-s3 tests.
If you are not sure how to test your pull request, you can ask the gem owners
to supplement the request with tests.
However, by including proper tests, you increase the chances of your pull
request being incorporated into future releases.
