Bash script to deploy/update/remove stacks in a [Portainer](https://portainer.io/) instance from a [docker-compose](https://docs.docker.com/compose) [yaml file](https://docs.docker.com/compose/compose-file).

## How to install

### Standalone

Just clone the repo and use the script:

```bash
git clone https://gitlab.com/psuapp/psu.git
cd psu/
bash ./psu deploy ...
```

For detailed instructions, see [How to use](#how-to-use) section.

#### Requirements

You will need these dependencies installed:

- [bash](https://www.gnu.org/software/bash/)
- [httpie](https://httpie.org/)
- [jq](https://stedolan.github.io/jq/)

For Debian and similar apt-powered systems: `apt install bash httpie jq`.

### Docker image and variants

If you don't want or can't install `psu` and its dependencies, you can run it with the default [published Docker image](https://hub.docker.com/r/psuapp/psu), like this:
```bash
docker run psuapp/psu deploy ...
```
> **Note**: Docker images are also available on [GitLab](https://gitlab.com/psuapp/psu/container_registry).

For detailed instructions, see [How to use](#how-to-use) section.

#### Supported tags

Published Docker images are [tagged](https://hub.docker.com/r/psuapp/psu/tags) matching [GitLab tags](https://gitlab.com/psuapp/psu/-/tags):

-	`dev` -> [`dev`](https://gitlab.com/psuapp/psu/-/tags/dev)
-	`1`, `1.0`, `1.0.0`, `latest` -> [`v1.0.0`](https://gitlab.com/psuapp/psu/-/tags/v1.0.0)
-	`0.1.1`, `latest` -> [`v0.1.1`](https://gitlab.com/psuapp/psu/-/tags/v0.1.1)
-	`0.1.0` -> [`v0.1.0`](https://gitlab.com/psuapp/psu/-/tags/v0.1.0)

##### Variants

The `core` variant doesn't include `docker-compose`, so it's a bit smaller.
But you can't lint Docker compose/stack file before deploying a stack.
-	`dev-core` -> [`dev`](https://gitlab.com/psuapp/psu/-/tags/dev)
-	`1-core`, `1.0-core`, `1.0.0-core`, `core` -> [`v1.0.0`](https://gitlab.com/psuapp/psu/-/tags/v1.0.0)

The `debian` and `debian-core` variants use [Debian](https://www.debian.org) instead of [Alpine](https://alpinelinux.org/) as base image for `psu`.
-	`dev-debian` -> [`dev`](https://gitlab.com/psuapp/psu/-/tags/dev)
-	`dev-debian-core` -> [`dev`](https://gitlab.com/psuapp/psu/-/tags/dev)
-	`1-debian`, `1.0-debian`, `1.0.0-debian`, `debian` -> [`v1.0.0`](https://gitlab.com/psuapp/psu/-/tags/v1.0.0)
-	`1-debian-core`, `1.0-debian-core`, `1.0.0-debian-core`, `debian-core` -> [`v1.0.0`](https://gitlab.com/psuapp/psu/-/tags/v1.0.0)


#### Testing/debugging:

For testing/debugging, you can use this Docker image in interactive mode, to run any commands inside the container:
```bash
docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -it --rm --entrypoint bash psuapp/psu
# Run any commands here! E.g.
$ psu --version
Portainer Stack Utils, version 1.0.0
  License GPLv3: GNU GPL version 3
```

## How to use

The provided `psu` script allows to deploy/update/remove... Portainer stacks. Settings can be passed through envvars and/or options and/or flags. Both envvars, options and flags can be mixed but options or flags will always overwrite envvar values. When deploying a stack, if it doesn't exist a new one is created, otherwise it's updated (unless strict mode is active).

### With options

This is more suitable for standalone script usage.

- `<action>` ("deploy", "rm", "ls"..., required): Whether to deploy, remove, list... the stack, _not an option but an argument_
- `--user` (string, required): Username
- `--password` (string, required): Password
- `--url` (string, required): URL to Portainer
- `--name` (string, required): Stack name
- `--compose-file` (string, required if action=deploy): Path to docker-compose file

For detailed instructions, see the full [options list](docs/README.md#available-options).

#### Examples

```bash
bash ./psu deploy --user admin --password password --url https://portainer.local --name mystack --compose-file /path/to/docker-compose.yml --env-file /path/to/env_vars_file
```

```bash
bash ./psu rm --user admin --password password --url https://portainer.local --name mystack
```

**With Docker:**
```bash
docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -v $(pwd)/.env:/.env psuapp/psu deploy --user admin --password password --url https://portainer.local --name mystack --compose-file docker-compose.yml --env-file .env
```

### With flags

This is more suitable for standalone script usage.

- `<action>` ("deploy", "rm", "ls"..., required): Whether to deploy, remove, list... the stack, _not a flag but an argument_
- `-u` (string, required): Username
- `-p` (string, required): Password
- `-l` (string, required): URL to Portainer
- `-n` (string, required): Stack name
- `-c` (string, required if action=deploy): Path to docker-compose file

For detailed instructions, see the full [flags list](docs/README.md#available-options).

#### Examples

```bash
bash ./psu deploy -u admin -p password -l https://portainer.local -n mystack -c /path/to/docker-compose.yml -g /path/to/env_vars_file
```

```bash
bash ./psu rm -u admin -p password -l https://portainer.local -n mystack
```

**With Docker:**
```bash
docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -v $(pwd)/.env:/.env psuapp/psu deploy -u admin -p password -l https://portainer.local -n mystack -c docker-compose.yml -g .env
```

### With envvars

This is particularly useful for [CI](https://en.wikipedia.org/wiki/Continuous_integration)/[CD](https://en.wikipedia.org/wiki/Continuous_deployment) pipelines using Docker containers.

- `ACTION` ("deploy", "rm", "ls"..., required): Whether to deploy, remove, list... the stack
- `PORTAINER_USER` (string, required): Username
- `PORTAINER_PASSWORD` (string, required): Password
- `PORTAINER_URL` (string, required): URL to Portainer
- `PORTAINER_STACK_NAME` (string, required): Stack name
- `DOCKER_COMPOSE_FILE` (string, required if action=deploy): Path to doker-compose file

For detailed instructions, see the full [envvars list](docs/README.md#available-environment-variables).

#### Examples

```bash
export ACTION="deploy"
export PORTAINER_USER="admin"
export PORTAINER_PASSWORD="password"
export PORTAINER_URL="https://portainer.local"
export PORTAINER_STACK_NAME="mystack"
export DOCKER_COMPOSE_FILE="/path/to/docker-compose.yml"
export ENVIRONMENT_VARIABLES_FILE="/path/to/env_vars_file"

bash ./psu
```

```bash
export ACTION="rm"
export PORTAINER_USER="admin"
export PORTAINER_PASSWORD="password"
export PORTAINER_URL="https://portainer.local"
export PORTAINER_STACK_NAME="mystack"

bash ./psu
```

**With Docker:**
```bash
docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -v $(pwd)/.env:/.env -e ACTION="deploy" -e PORTAINER_USER="admin" -e PORTAINER_PASSWORD="password" -e PORTAINER_URL="https://portainer.local" -e PORTAINER_STACK_NAME="mystack" -e DOCKER_COMPOSE_FILE="docker-compose.yml" -e ENVIRONMENT_VARIABLES_FILE=".env" psuapp/psu
```
