How to install

Standalone

Note

: The easiest way to install psu is to use Docker method, instead of this one

Check the Requirements section then git clone the repo and use the bash script below:

git clone https://gitlab.com/psuapp/psu.git
cd psu/
# Allow the 'psu' command to run everywhere:
export PATH="$(pwd):$PATH"
# Or if you want it permanent, with a super user account, run:
# ln -s $(pwd)/psu /usr/local/bin
#
# Then you can use psu, e.g.
psu deploy ...

For detailed instructions, see How to use section.

Requirements

You will need these dependencies installed:

Linux based systems (Alpine, Debian, Ubuntu...)

• bash^* (>= 4.4.23)
• curl^* (>= 7.64.0, but >= 7.76.0 is recommended)
• jq^* (>= 1.5.1)
• uuidgen recommended only for some OS (Alpine and Debian work fine without it)

For Debian and similar apt-powered Linux systems, run: apt install bash curl jq

macOS

• bash^* (>= 4.4.23)
• curl^* (>= 7.64.0, but >= 7.76.0 is recommended)
• jq^* (>= 1.5.1)
• timeout^* (included in the coreutils package)
• greadlink (included in the coreutils package)

You should install Homebrew, then run: brew install bash coreutils jq

Windows

• bash^* (>= 4.4.23)
• curl^* (>= 7.64.0, but >= 7.76.0 is recommended)
• jq^* (>= 1.5.1)

Note

: psushould work with Windows, but it could be unstable ⚠️

You should download and install Git and jq for Windows

For all systems

• docker-compose is recommended but not required (useful for linting docker compose/stack files)

^* = required

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, like this:

docker run psuapp/psu:1.2 deploy ...

Note

: Docker images are also available on GitLab.

For detailed instructions, see How to use section.

Supported tags

Published Docker images are tagged matching GitLab tags:

• 1.3.0-alpha -> v1.3.0-alpha
• 1, 1.2, 1.2.0 -> v1.2.0
• 1.2.0-beta.1 -> v1.2.0-beta.1
• 1.2.0-alpha -> v1.2.0-alpha
• 1.1, 1.1.0 -> v1.1.0
• 1.1.0-alpha -> v1.1.0-alpha
• 1.0, 1.0.7 -> v1.0.7
• 1.0.6 -> v1.0.6
• 1.0.5 -> v1.0.5
• 1.0.4 -> v1.0.4
• 1.0.3 -> v1.0.3
• 1.0.2 -> v1.0.2
• 1.0.1 -> v1.0.1
• 1.0.0 -> v1.0.0
• 0.1.2 -> v0.1.2
• 0.1.1 -> v0.1.1
• 0.1.0 -> 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.

• 1-core, 1.2-core, 1.2.0-core -> v1.2.0
• 1.1-core, 1.1.0-core -> v1.1.0
• 1.0-core, 1.0.7-core -> v1.0.7

The debian and debian-core variants use Debian instead of Alpine as base image for psu.

• 1-debian, 1.2-debian, 1.2.0-debian -> v1.2.0
• 1-debian-core, 1.2-debian-core, 1.2.0-debian-core -> v1.2.0
• 1.1-debian, 1.1.0-debian -> v1.1.0
• 1.1-debian-core, 1.1.0-debian-core -> v1.1.0
• 1.0-debian, 1.0.7-debian -> v1.0.7
• 1.0-debian-core, 1.0.7-debian-core -> v1.0.7

Testing/debugging:

For testing/debugging, you can use this Docker image in interactive mode, to run any commands inside the container:

docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -it --rm --entrypoint bash psuapp/psu:1.2
# Run any commands here! E.g.
$ psu --version

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.

Examples

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

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

With Docker:

docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -v $(pwd)/.env:/.env psuapp/psu:1.2 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.

Examples

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

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

With Docker:

docker run -v $(pwd)/docker-compose.yml:/docker-compose.yml -v $(pwd)/.env:/.env psuapp/psu:1.2 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/CD 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 docker-compose file

For detailed instructions, see the full envvars list.

Examples

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"

psu

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

psu

With Docker:

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:1.2
