#dokku

hey, I am running a nodejs server inside dokku, but nginx is dropping the cookie header -- but only from the websockets

cookies?

there are no cookies for websocket, just on handshake

hi, i've installed dokku, setup 2 node apps with no problem. even added mongodb plugin and works fine. The third app doesn't wan't to work :-S 'dokku enter' and do a curl http://localhost:5000/ works fine... from the host curl http://<app_ip>:5000/ says connection refused

I am freaking confused where to start with Docker

every article branches out to 10 more softwares

now I am suddenly reading about Dokku, Flynn and Dies

Deis*

can someone link me to a high level overview of why I need dokku?

[michaelshobbs] some old posts i found

[michaelshobbs] https://www.andrewmunsell.com/blog/dokku-tutori...

[michaelshobbs] http://donpottinger.net/blog/2014/11/17/bye-bye...

[michaelshobbs] the easy answer is simplicity vs the others

[Martin Triay] hello

[Martin Triay] I'm having issues trying to authorize my dokku instance to pull from private repos in github

[Martin Triay] ```~# dokku version

0.5.6```

[Martin Triay] already tried generating keys with https://github.com/cedricziel/dokku-deployment- keys

[Jose Diaz-Gonzalez] you need both the deployment keys and hostkeys plugin

[Martin Triay] ok

[Martin Triay] but why?

[Martin Triay] isnt the hostketys plugin for authorized_keys?

[Martin Triay] if i understand correctly, that's only to push into dokku

[Martin Triay] not for pulling from github to dokku

[Martin Triay] this is the output i'm getting from shippable (CI)

[Martin Triay] ```remote: npm ERR! Cloning into bare repository '/app/.npm/_git-remotes/git-ssh-git-github-com-benchrise-benchrise-common-git-ef7350ab'...

remote: npm ERR! Host key verification failed.

remote: npm ERR! fatal: Could not read from remote repository.

remote: npm ERR!

remote: npm ERR! Please make sure you have the correct access rights

remote: npm ERR!

remote: npm ERR!

remote: npm ERR! If you need help, you may report this error at:

[Martin Triay] it looks like i'm being able to push the app into dokku

[Martin Triay] but dokku is not being able to pull from github the private repos

[Martin Triay] in this case, `remote` stands for the dokku instance

[michaelshobbs] =D

[michaelshobbs] specifically this

```

remote: npm ERR! Host key verification failed.

```

[michaelshobbs] https://github.com/cedricziel/dokku-hostkeys-pl...

[michaelshobbs] ```

Manage hostkeys (for .ssh/known_hosts) to your container environment

This is useful if you hide your sourcecode in private repositories at VCS providers such as GitHub or Bitbucket.

You probably need something to manage your deployment keys as well. Checkout dokku-deployment-keys

```

[Martin Triay] @michaelshobbs: @savant thanks! it worked

[Martin Triay] but i'm not sure why it did

[Martin Triay] without the plugin dokku does not accept any new host?

[michaelshobbs] because ssh

[Jose Diaz-Gonzalez] ^

[Jose Diaz-Gonzalez] This isn't specific to dokku

[Jose Diaz-Gonzalez] You'd have to do the same on your own hosting infrastructure

[michaelshobbs] reading up on ssh/git/docker/nginx/etc will help

[Jose Diaz-Gonzalez] in my case, we have the host have a key that is tied to a deploy user which is then attached to all repositories.

[michaelshobbs] but if it works, it works

Hi, friends! I currently have a Dokku setup on DO, and everything is running quite good (awesome app, btw!). But... I'm a bit lost when it concerns to send email though a container. For example: Is there a way I can send emails though, let's say, the Postfix I do have installed on my server? Thanks in advance, I'm kinda newbie on Docker/Dokku yet! Thanks, friends.

*through

you dont talk to the host

it has to be within the container

so if you have postfix on the host, that doesnt matter to your application

if you wanted postfix on the container, you'd need the dokku-apt plugin to set that up (its linked to in our docs on community plugins)

[michaelshobbs] you can talk to the host depending on how you have your networking setup

[michaelshobbs] you could also mount the mail dir and write messages for postfix to handle

[michaelshobbs] or install postfix in the container as savant suggested

Hmmm... Thanks @savant! The idea of have postfix @ container seems good to me. I'm running some PHP apps using composer, never did anything Docker related (only a few "hello world" apps. :\ ). So... there's a Dokku Postfix plugin, or, if not, what is the better way that I can "point" my container to install it? Thanks again!

there isnt a plugin for just postfix. you'll want to install the dokku-apt plugin to manage apt dependencies within your app

*or* use a hosted service for sending email

up to you

im headed out, good luck!

Oh, i see now. Just needed to be pointed on the right direction. Thanks, i'll do it!

^ there you go

the apt plugin is in that list

Good, just installed the plugin. Thanks too, gliderlabs!
