Assumes that you use Ubuntu 14.04 LTS right now. Ideally, you should have a domain ready to point to your host. It's designed for and is probably best to use a fresh VM. The debian package will install everything it needs.
$ sudo bash -c "$(curl -fsSL https://raw.githubusercontent.com/dokku-alt/dokku-alt/master/bootstrap.sh)"
Sometimes you may want to install dokku-alt in a completely non-interactive way. Now you can do it. Simply boostrap.sh without terminal:
$ sudo bash -c "$(curl -fsSL https://raw.githubusercontent.com/dokku-alt/dokku-alt/master/bootstrap.sh)" < /dev/null
If you use the bootstrap script from above, at the end it will fireup ruby installation script. Point your browser to http://<ip>:2000/ and finish configuration.
That's it!
Set up a domain and a wildcard domain pointing to that host. Make sure /home/dokku/VHOST is set to this domain. By default it's set to whatever hostname the host has. This file is only created if the hostname can be resolved by dig (dig +short $(hostname -f)). Otherwise you have to create the file manually and set it to your preferred domain. If this file still is not present when you push your app, dokku will publish the app with a port number (i.e. http://example.com:49154 - note the missing subdomain).
You'll have to add a public key associated with a username by doing something like this from your local machine:
$ cat ~/.ssh/id_rsa.pub | ssh dokku.me sudo dokku access:add
Unlike dokku, this script uses the debian packaging system (deb). To upgrade to the latest version, simply execute: sudo apt-get update && sudo apt-get install dokku-alt.
Alongside the normal (stable) releases we distribute as well beta (bleeding edge). To switch to beta simply execute: sudo apt-get update && sudo apt-get install dokku-alt-beta. It will replace the stable dokku-alt and switch to beta.
It should be possible, it should mostly work, but it's not tested and advised. VPS's are very cheap this days so fire-up new machine and setup dokku-alt from scratch.
Now you can deploy apps on your Dokku. Let's deploy the Heroku Node.js sample app. All you have to do is add a remote to name the app. It's created on-the-fly. Note that you must use the username dokku@yourhostname.com:your-repository-name if you used the boostrap.sh script to install dokku-alt.
$ git clone https://github.com/heroku/node-js-sample
$ cd node-js-sample
$ git remote add dokku dokku@dokku-alt.com:node-js-app
$ git push dokku master

You're done!
Right now Buildstep supports buildpacks for Node.js, Ruby, Python, and more. It's not hard to add more, go add more! Please check the documentation for your particular build pack as you may need to include configuration files (such as a Procfile) in your project root.
It's a web interface to easily manage your dokku-alt instance. To install manager, simply run:
dokku manager:install
You can enable or disable it anytime:
dokku manager:enable
dokku manager:disable
Or even uninstall if you prefer command line access (it will also wipe used database):
dokku manager:uninstall
Dokku-alt can be run using Docker-in-Docker approach (https://github.com/jpetazzo/dind). It requires you to run the dokku-alt container in privileged mode (with full access to host), because dokku-alt uses its own Docker daemon to serve applications. It's still considered beta, but should be pretty safe solution and robust. It's best to use for play with dokku-alt on other not-supported systems (CentOS, RedHat, Debian) or by simply trying how it works.
All dokku-alt services (SSH, Nginx, Dokku daemon) are run in container.
docker run --volume=/home/dokku --volume=/var/lib/docker --name=dokku-alt-data busybox:latest
docker run -d --name=dokku-alt --hostname=my-domain.com --volumes-from=dokku-alt-data --publish=22:22 --publish=80:80 --publish=443:443 --privileged ayufan/dokku-alt:latest
You can adjust the exposed ports as described in Docker documentation.
docker logs dokku-alt-demo
At the end, you should see something like this:
dokku.1 | SSH Login:
dokku.1 | user: root
dokku.1 | password: lfMUjxYEvqpRRLY6
dokku.1 | ip: 10.0.42.1 172.17.2.213
dokku.1 | Starting dokku daemon...
This is a temporary root password to access the container and add your access keys (using dokku access:add as described). This password changes every container restart.
To enter the container shell from the server's terminal (the same which is running docker with dokku-alt) run ssh:
ssh root@172.17.2.213
If everything was done right, you should see the container's prompt. By exposing ports in docker run to the outside world you can also access dokku-alt externally.
docker kill dokku-alt
docker pull ayufan/dokku-alt:latest
docker run -d --name=dokku-alt --hostname=my-domain.com --volumes-from=dokku-alt-data --publish=22:22 --publish=80:80 --publish=443:443 --privileged ayufan/dokku-alt:latest
The key feature of dokku-alt is built-in support for Dockerfiles, the docker build process. It allows you to create more advanced and more repetitive application environments.
To use Dockerfile simply put Dockerfile in root of the application, dokku-alt will detect it and build application according to specification in Dockerfile.
Dockerfile-based application can (but not required) expose a web-application port. dokku-alt will check if port 80, 8080 or 5000 is exposed. If it is, it will update the assigned vhost and reconfigure nginx to forward all incoming traffic.
Using Dockerfile, you can build service-only applications. Simply don't expose any public facing ports.
Example Dockerfile application: https://github.com/ayufan/dokku-alt-phpmyadmin
Dokku-alt has built-in support for additional domains and url redirects. By specifying redirects, any client using that address will automatically be redirected to the first domain assigned to the application.
Dokku commands can be run over ssh. Anywhere you would run dokku <command>, just run ssh -t dokku@progriumapp.com <command>
The -t is used to request a pty. It is highly recommended to do so.
To avoid the need to type the -t option each time, simply create/modify a section in the .ssh/config on the client side, as follows :
Host progriumapp.com
RequestTTY yes
It's possible to run commands in the environment of the deployed application:
$ dokku run node-js-app ls -alh
$ dokku run <app> <cmd>
SSH onto the server, then execute:
$ dokku delete myapp
Dokku-alt allows you to create an application before pushing it. It can be useful when you want to specify additional config variables or assign databases. Simply execute:
$ dokku create mynewapp
It's also possible to disable auto-application creation on push. Add to ~/dokkurc:
export DOKKU_DISABLE_AUTO_APP_CREATE=1
From now on you will have to do dokku create before pushing.
Dokku-alt allows you to add additional public keys to applications. The specific case is to add special deploy-only key, used for example by Countinous Integration (ie. Jenkins). Key added as deploy-only can only be used to git push specific application. It will not allowed to execute any dokku commands. You can add an ssh key and give it explicit access to one or many applications.
Add locally:
$ cat .ssh/id_rsa.pub | dokku deploy:allow myapp
Add key remotely:
$ cat .ssh/id_rsa.pub | ssh dokku@dokku deploy:allow myapp
To later revoke key execute:
$ dokku deploy:revoke myapp FINGERPRINT
You can also list all fingerprints allowed to deploy an application:
$ dokku deploy:list myapp
Add a new admin user:
$ cat .ssh/id_rsa.pub | dokku access:add
Revoke permissions for admin user:
$ dokku access:revoke FINGERPRINT
Typically, an application will require some environment variables to run properly. Environment variables may contain private data, such as passwords or API keys, so it is not recommend to store them in your application's repository.
The config plugin provides the following commands to manage your variables:
config <app> - display the config vars for an app
config:get <app> KEY - display a config value for an app
config:set <app> KEY1=VALUE1 [KEY2=VALUE2 ...] - set one or more config vars
config:unset <app> KEY1 [KEY2 ...] - unset one or more config vars
DOKKU_NGINX_PROXY_READ_TIMEOUT- allows to overridenginx proxy_read_timeout. Default value is set to '60s'. For more info please refer to: http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout.DOKKU_ENABLE_HTTP_HOST- when set to 1, the application will also serve content on HTTP if HTTPS is enabledDOKKU_BUILDSTEP_IMAGE- allows you to set a custom buildstep image on per app basis. Image has to be compatible with https://github.com/progrium/buildstep or https://github.com/dokku-alt/progrium-buildstep-dockerfiles. If the images was forked from https://github.com/progrium/buildstep, there might be a small incompatibility: the image is run with/startinstead of/start webas in orginaldokku.DOKKU_START_CMD- allows you to set a custom start command. The default value is/startfor buildstep images and
When you successfully deploy an app, you can tag it with a name/version. This lets you quickly roll back to that image in the event of failure in a later deployment.
$ dokku tag:add gitlab v6.9.0
=====> Tagged latest image of dokku/gitlab as v6.9.0
$ dokku tag:list gitlab
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
dokku/gitlab build fc3baf1216d2 4 weeks ago 954.9 MB
dokku/gitlab latest fc3baf1216d2 4 weeks ago 954.9 MB
dokku/gitlab release fc3baf1216d2 4 weeks ago 954.9 MB

$ dokku deploy gitlab release <-- it will deploy GIT head
$ dokku deploy gitlab v6.9.0 <-- it will deploy tagged image
Dokku-alt has built-in support for all modern database engines: MariaDB (former MySQL), PostgreSQL and MongoDB. The database image will be downloaded and provisioned when first used.
First create a database:
$ dokku mariadb:create test-db
-----> MariaDB database created: test-db
Second link the database to an app:
$ dokku mariadb:link node-js-sample test-db
-----> Releasing node-js-sample ...
-----> Deploying node-js-sample ...
-----> Shutting down old containers
=====> Application deployed:
http://node-js-sample.ayufan.eu
Verify the application environment variables:
$ dokku config node-js-sample
=== node-js-sample config vars ===
DATABASE_URL: mysql2://node-js-sample:random-password@mariadb:3306/test-db
To use a different database engine, simply replace mariadb with postgresql or mongodb.
Similar to functionality provided by https://devcenter.heroku.com/articles/labs-preboot dokku-alt supports zero-downtime. To enable zero-downtime deployment, execute command: dokku preboot:enable APP. Alongside with preboot, there's a checks plugin based on https://labnotes.org/zero-downtime-deploy-with-dokku/. For now, it simply checks if the application started serving requests. If the checks module fails, it will not replace the application.
Preboot and checks can be configured using a few environment variables:
- PREBOOT_WAIT_TIME - number of seconds to wait for container boot (default 5s)
- PREBOOT_COOLDOWN_TIME - number of seconds to wait finish container request processing (default 30s)
- DOKKU_CHECKS_WAIT - number of seconds to wait before request retries (default 10s)
- DOKKU_CHECKS_TIMEOUT - number of seconds to wait for each response (default 20s)
- DOKKU_CHECKS_RETRY - number of retries (default 3)
Docker allows you to have persistent data storage. Dokku-alt exposes this feature as Data Volumes. You can create unlimited number of data volumes and any data volume can be attached to unlimited number of apps. Simply create a data volume and specify container paths which you want to be persistant.
First, create a data volume:
$ dokku volume:create shared-test-volume /app/logs /app/tmp /app/uploads
-----> Volume created: volume_data_shared-test-volume
Second, link the volume to an app:
$ dokku volume:link node-js-sample shared-test-volume
-----> Volume shared-test-volume linked to an aplication: node-js-sample
-----> Releasing node-js-sample ...
-----> Deploying node-js-sample ...
-----> Shutting down old containers
=====> Application deployed:
http://node-js-sample.ayufan.eu
It is just simple as this.
Dokku-alt allows you to bind host-based volumes in a very simple manner. To use this feature, you have to be logged as root and then simply type:
dokku volume:create host-based-volume /path/to/host/volume:/path/to/volume/in/container
Dokku-alt allows you to secure any application with HTTP-Basic Auth. There are a few commands that makes it happen:
htpasswd:add <app> <user> Add http-basic auth user
htpasswd:disable <app> Remove http-basic Auth
htpasswd:remove <app> <user> Remove user
If you want to enable and add a new user, simply type the command below and when prompted, type your password twice:
dokku htpasswd:add myapp myuser
You can also pipe the password:
echo mypass | dokku htpasswd:add myapp myuser
To revoke user's permission:
dokku htpasswd:remove myapp
To remove HTTP-Basic Auth completely:
dokku htpasswd:disable myapp
Dokku provides easy TLS support out of the box. To enable TLS connection to your application, copy the .crt and .key files into the /home/dokku/:app/ssl folder (notice, file names should be server.crt and server.key, respectively). Redeployment of the application will be needed to apply TLS configuration. Once it's redeployed, the application will be accessible by https:// (redirection from http:// is applied as well).
Dokku-alt extends this even further by allowing you to use command line interface for certificates:
ssl:generate <app> Generate certificate signing request for an APP
ssl:certificate <app> Pipe signed certifcate with all intermediates for an APP
ssl:forget <app> Wipes certificate for an APP
ssl:info <app> Show info about certifcate and certificate request
ssl:key <app> Pipe private key for an APP
First use: dokku ssl:generate myapp to generate certificate signing request (CSR). At the end of process you will receive BEGIN CERTIFICATE REQUEST which you can ten copy-n-paste to your SSL signer (ie. http://startssl.com).
When you receive your signed certificate pipe it with ALL INTERMEDIATES to dokku ssl:certificate myapp. If done correctly you have SSL enabled for your site.
cat mycert.pem intermediate.pem ca.pem | dokku ssl:certificate myapp
If it happens that you have already created certificate you can use it, by piping your UNENCRYPTED your certificate and your private key:
cat mycert.pem intermediate.pem ca.pem | dokku ssl:certificate myapp
cat mycert.key | dokku ssl:key myapp
To view asigned certificate:
dokku ssl:info myapp
HTTP Strict Transport Security (HSTS) is a web security policy mechanism whereby a web server declares that complying user agents (such as a web browser) are to interact with it using only secure HTTPS connections. Once enabled all further communication will be done over TLS only, there's no revert mechanism. As this is additional security feature you have to do it by hand. To enable HSTS for site use:
dokku config:set myapp DOKKU_ENABLE_HSTS=1
By default dokku-alt for all TLS-enabled apps will create redirects which requires user to use https://. In some cases it maybe required to allow http:// access which is potentially insecure. To enable simulatenous HTTP and HTTPS set specific config:
dokku config:set myapp DOKKU_ENABLE_HTTP_HOST=1
You can fine-tune some aspects of Dokku behaviour and its plugins by setting variables in dokkurc file placed in Dokku root directory – usually /home/dokku. dokkurc is sourced by the main dokku script.
Example:
export DOKKU_DISABLE_AUTO_APP_CREATE=1
export BUILDSTEP_IMAGE="ayufan/dokku-alt-buildstep:foreman"
DOKKU_DISABLE_AUTO_APP_CREATE– when set to1, applications won't be automatically created on push; see Create only application.BUILDSTEP_IMAGE– buildstep image to be used by Docker, defaults toayufan/dokku-alt-buildstep:foreman.MARIADB_IMAGE– Docker image to be used for MariaDB plugin, defaults toayufan/dokku-alt-mariadb.MONGODB_IMAGE– Docker image to be used for MongoDB plugin, defaults toayufan/dokku-alt-mongodb.POSTGRESQL_IMAGE– Docker image to be used for PostgreSQL plugin, defaults toayufan/dokku-alt-postgresql.REDIS_IMAGE– Docker image to be used for Redis plugin, defaults toayufan/dokku-alt-redis.DOKKU_LISTEN_IPV4- Set the IPV4 address on which NGINX will listen for requestsDOKKU_LISTEN_IPV6- Set the IPV6 address on which NGINX will listen for requestsDOKKU_FORCE_ENABLE_HSTS- Force to enable HSTS header (validity for one year) for all TLS-enabled appsDOKKU_DISABLE_NGINX_X_FORWARDED- Disable setting ofX-Forwardedheaders by nginx, useful for CDN installations.

"I deployed my Rails application on a fresh new machine using dokku-alt but I already own a bare metal, replicated PostgreSQL server that's reachable from the dokku host as it's on the same network. How do I connect?"
Run the following:
dokku config:set <app> DATABASE_URL=postgresql://user:password@dbserver-ip:5432/DBNAME
You have to feed application with your DATABASE_URL. You can even use databases from heroku.
You can create file: /home/dokku/APPNAME/DOCKER_ARGS and fill it with additional arguments as described in http://docs.docker.com/reference/run/. These arguments will be injected when deploying the application or invoking dokku run.
The following error typically occurs on boxes with 512MB of memory:
runtime: panic before malloc heap initialized
fatal error: runtime: cannot allocate heap metadata
Run the following (it will create 512MB swap file, you can adjust it for your needs):
dd if=/dev/zero of=/extraswap bs=1M count=512
mkswap /extraswap
Add it to /etc/fstab:
/extraswap none swap sw 0 0
