# Rundeck Docker Compose files
Docker Compose files to spin up an instance of Rundeck.
# How to run
Add a `COMPOSE_ENV` file and save its location as a shell variable along with the location where this repo lives, here for example `/opt/containers/rundeck` plus all other variables. At [env/fqdn_context.env.example](env/fqdn_context.env.example) you'll find an example environment file.
When everything's ready start Rundeck with Docker Compose, otherwise head down to [Initial setup](#initial-setup) first.
## Environment
```
export COMPOSE_DIR='/opt/containers/rundeck'
export COMPOSE_CTX='ux_vilnius'
export COMPOSE_PROJECT='rundeck-'"${COMPOSE_CTX}"
export COMPOSE_FILE="${COMPOSE_DIR}"'/docker-compose.yml'
export COMPOSE_ENV=<add accordingly>
```
## Start
```
docker compose --project-name "${COMPOSE_PROJECT}" --file "${COMPOSE_FILE}" --env-file "${COMPOSE_ENV}" --profile 'full' up --detach
```
# Initial setup
We're assuming you run Docker Compose workloads with ZFS-based bind mounts. ZFS management, creating a zpool and setting adequate properties for its datasets is out of scope of this document.
## Datasets
Create ZFS datasets and set permissions as needed.
* Parent dateset
```
zfs create -o mountpoint=/opt/docker-data 'zpool/docker-data'
```
* Container-specific datasets
```
zfs create -p 'zpool/docker-data/rundeck-'"${COMPOSE_CTX}"'/rundeck'
zfs create -p 'zpool/docker-data/rundeck-'"${COMPOSE_CTX}"'/postgres'
```
* Create subdirs
```
mkdir -p '/opt/docker-data/rundeck-'"${COMPOSE_CTX}"'/rundeck/'{'.ssh','config','data','projects'}
```
* Prefill content
* Rundeck settings in `realm.properties`
At the very least override Rundeck's default `realm.properties` file with one of your own and set a username and a password for local login. Default credentials will otherwise be `admin:admin`. Per [Rundeck's manual on Jetty and JAAS authentication section "PropertyFileLoginModule"](https://docs.rundeck.com/docs/administration/security/authentication.html#propertyfileloginmodule) you're going to need Rundeck's `rundeck.war` file to create a bcrypt hash for your password. Run the official Rundeck Docker image in a throwaway container like so where `rundeck/rundeck:4.13.0` is an example version you want to use:
```
docker run \
--rm \
--tty \
--interactive \
--entrypoint bash \
rundeck/rundeck:4.13.0 \
-c 'java -jar /home/rundeck/rundeck.war --encryptpwd Jetty'
```
This will download `rundeck/rundeck:4.13.0` if needed and open up something along the lines of:
```
Required values are marked with: *
Username (Optional, but necessary for Crypt encoding):
```
Type your desired username, type `<Enter>` and then your plain text password followed by `<Enter>` again. The whole exchange may look like this:
```
Required values are marked with: *
Username (Optional, but necessary for Crypt encoding):
my-username
*Value To Encrypt (The text you want to encrypt):
t0psecr3t
==ENCRYPTED OUTPUT==
bcrypt: BCRYPT:$2a$10$jMWQvKbjpmBrKdA0Qi0/n.UvHot1F7Cvf7/Avlv9afknHpbvT6j7y
obfuscate: OBF:1z0f18qk1xtp1vgv1t331vfz1xtt18qq1z0f
md5: MD5:962aefc8c283c13e13d9c990dafdfba9
crypt: CRYPT:myS5y0c4wMQts
```
Put a single line into an otherwise empty `/opt/docker-data/rundeck-'"${COMPOSE_CTX}"'/rundeck/config/realm.properties`:
```
my-username: BCRYPT:$2a$10$jMWQvKbjpmBrKdA0Qi0/n.UvHot1F7Cvf7/Avlv9afknHpbvT6j7y,user,admin
```
The account `my-username` will have roles `user` and `admin` and it'll be the only existing account when Rundeck starts.
* SSH `known_hosts` file
Place an empty `known_hosts` file at `/opt/docker-data/rundeck-'"${COMPOSE_CTX}"'/rundeck/.ssh/known_hosts`. Feel free to optionally prefill it with SSH public host keys.
* Change ownership
```
chown -R 999 '/opt/docker-data/rundeck-'"${COMPOSE_CTX}"'/postgres'
chown -R 1000 '/opt/docker-data/rundeck-'"${COMPOSE_CTX}"'/rundeck'
```
When done head back up to [How to run](#how-to-run).
