 1 | # dokku-post-deploy-script
 2 | 
 3 | Dokku plugin to execute scripts on dokku host after a deploy
 4 | 
 5 | ## requirements
 6 | 
 7 | - dokku 0.4.0+
 8 | 
 9 | ## installation
10 | 
11 | ```shell
12 | # on 0.4.x
13 | dokku plugin:install https://github.com/baikunz/dokku-post-deploy-script.git post-deploy-script
14 | ```
15 | 
16 | ## hooks
17 | 
18 | This plugin provides hooks:
19 | 
20 | * `post-deploy`: Execute script on dokku host after deploy
21 | 
22 | ## usage
23 | This plugin allows you to execute on your host a script which reside in the `$DOKKU_ROOT/$APP/` after a deploy.
24 | 
25 | The file must be named `POST_DEPLOY_SCRIPT`.
26 | 
27 | ## example
28 | 
29 | Two dokku apps need to communicate with each other. In order to do so we have to create a common network and attach both of our apps that common network.
30 | 
31 | However, after every deploy, the newly created container won't be reattached automatically, and you'll have to do that manually, or using this plugin you can create in both of those apps a `POST_DEPLOY_SCRIPT` that will do that for you.
32 | 
33 | In `$DOKKU_ROOT/firstapp/POST_DEPLOY_SCRIPT` for the first app
34 | 
35 | ```shell
36 | #!/bin/bash
37 | NETWORK_NAME='common-network'
38 | 
39 | # Create network if it does not exists
40 | NETWORK=$(docker network ls -q -f name="$NETWORK_NAME")
41 | [[ -z "$NETWORK" ]] && docker network create "$NETWORK_NAME"
42 | 
43 | # Connect to the network
44 | docker network connect "$NETWORK_NAME" firstapp.web.1
45 | ```
46 | 
47 | In `$DOKKU_ROOT/secondapp/POST_DEPLOY_SCRIPT` for the second app
48 | 
49 | ```shell
50 | #!/bin/bash
51 | NETWORK_NAME='common-network'
52 | 
53 | # Create network if it does not exists
54 | NETWORK=$(docker network ls -q -f name="$NETWORK_NAME")
55 | [[ -z "$NETWORK" ]] && docker network create "$NETWORK_NAME"
56 | 
57 | # Connect to the network
58 | docker network connect "$NETWORK_NAME" secondapp.web.1
59 | ```
