# gitea in a stack with drone and guacamole
|
|
|
|
Remote system support.
|
|
|
|
Consisting of
|
|
|
|
* gitea repository - github like self hosted git and web application
|
|
* drone ci system
|
|
* guacamole - rdp, vnc and ssh over the internet in the browser
|
|

(nb when self deploying with drone it will will stick on started and have to be cancelled. This is because the deployment tears down the previous running drone).
|
|
|
|
NB each time you deploy this using drone it will leave an orphaned network for example:
|
|
|
|
eventually this will start to cause an error with message: Docker “ERROR: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network”
|
|
|
|
You need to keep clearing out orphaned networks.
|
|
|
|

|
|
### labels
|
|
|
|
get nodes with
|
|
|
|

|
```
|
|
|
|
### generate certificates
|
|
|
|
(rnd file) dd if=/dev/urandom of=~/.rnd bs=256 count=1
|
|
where [registry-domain] is the domain on which the registry will be served
|
|
|
|
sh ca.sh [registry-domain]:5000
|
|
|
|
|
|
sh make-cert.sh [registry-domain] registry
|
|
|
|
### ngrok auth
|
|
|
|
obtain ngrok auth token and place in .secrets in form
|
|
|
|
authtoken: [token]
|
|
|
|
### initial deploy
|
|
|
|
```shell
|
|
export LOCAL_DOCKER_REGISTRY=registry.local-domain:5000
|
|
export CERTBOT_EMAIL=giles.bradshaw@sigyl.com
|
|
export GIT_DOMAIN=git.sigyl.com
|
|
export REMOTE_DOMAIN=remote.sigyl.com
|
|
export DRONE_DOMAIN=drone.sigyl.com
|
|
export BLOG_DOMAIN=blog.sigyl.com
|
|
|
|
export DRONE_RPC_SECRET=$(openssl rand -base64 48)
|
|
docker stack deploy -c docker-compose.yml gitea
|
|
```
|
|
|
|
### create gitea drone app with client id and secret
|
|
|
|
### add secrets to repository in drone
|
|
|
|
|
|
|
|
|
|
* blog-domain
|
|
* certbot-email
|
|
* drone-domain
|
|
* drone-gitea-client-id
|
|
* drone-gitea-client-secret
|
|
* drone-rpc-secret
|
|
* git-domain
|
|
* local-docker-registry
|
|
* remote-domain
|
|
* ssh-password
|
|
* ssh-port
|
|
* ssh-root-password

|
### kill orphan docker:dind containers
|
|
|
|
Wen the system is deployed by pushing to repository the docker:dind container will be orphaned and will run forever unless killed..
|
|
|
|
|
|
## guacamole
|
|
|
|
np no spaces in postgres password
|
|
|
|
docker stack for guacamole

adapted from https://digitalmccullough.com/posts/setting-up-apache-guacamole-with-docker-stack.html
|
|
|
|
### initialising
|
|
|
|
find id
|
|
|
|
```

|
docker ps
|

|
|
```
|
|
|
|
execute initdb.sql
|
|
|
|
```
|

docker exec -it $ID psql -U postgres -d guacamole_db -f /initdb.sql
|
|
docker exec -it $ID psql -U postgres -d guacamole_db -f /init-user.sql -v password='somepassword' -v user='guacamole_user'
|
|
```
|
|
|
|
initial admin is guacadmin:guacadmin
|
|
|

## docker-exec-runner on windows
|
|
|
|
These instructions are not very good...
|
|
|
|
https://exec-runner.docs.drone.io/installation/windows/
|
|
|
|
download and unpack on linux with
|
|
|
|
```
|
|
curl -L https://github.com/drone-runners/drone-runner-exec/releases/latest/download/drone_runner_exec_windows_amd64.tar.gz | tar zx
|
|
```
|
|
|
|
|
|
rename drone-runner-exec to drone-runner-exec.exe
|
|
|
|
make directory c:\Drone\drone-runner-exec on windows
|
|
|
|
copy drone-runner-exec.exe to directory
|
|
|
|
make config file with
|
|
|
|
```
|
|
|
|
DRONE_RPC_PROTO=https
|
|
DRONE_RPC_HOST=drone.sigyl.com:443
|
|
DRONE_RPC_SECRET=[rpc secret]
|
|
DRONE_LOG_FILE=C:\Drone\drone-runner-exec\log.txt
|
|
DRONE_RUNNER_LABELS=web:true
|
|
```
|
|
|
|
|
|
install and start service with
|
|
|
|
```
|
|
drone-runner-exec service install
|
|
drone-runner-exec service start
|
|
```
|
|
|
|
## chat
|
|
|
|
Once the chat-mongo container is up you need to get its id and do
|
|
|
|
```
|
|
docker exec -it [id] mongo --eval "printjson(rs.initiate({_id: 'rs0', members: [ { _id: 0, host: 'localhost:27017' } ]}))"
|
|
```
|
|
|
|
then scale up chat
|
|
|
|
```
|
|
docker service scale gitea_chat=1
|
|
``` |
