Report issueNotes
openssl rand -hex 32 makes one), since the stack won't start without it. Then open http://<your-host>:5150 (or whichever port you picked), which goes straight to a first-run page for the admin account. It wants a boot code from the container's logs: search them for Boot Code. After that, anyone who can reach it can push without an account, and sign up for one too. To stop either, add PWPUSH_ANONYMOUS = false or PWPUSH_DISABLE_SIGNUPS = true to the stack's environment variables and redeploy. Pushes, files and accounts live in the pwpush-storage volume. Text is encrypted with the master key there, but uploaded files are kept as they are. Docs: docs.pwpush.comStandalone Install

→ Setup a DNS record to point to your server (e.g.
pwpush.example.com) and run:docker run -d -p "80:80" -p "443:443" --env TLS_DOMAIN=pwpush.example.com pglombardo/pwpushand browse to

Password Pusher on:
Check the logs first
Nine times out of ten the logs tell you exactly what went wrong.
- In Portainer, go to Containers, click the container, then Logs. Or run
docker logs <container> - Exit codes help too:
137means killed, usually out of memory.126or127means the command inside the image is broken.
Image won't pull
Test the pull directly on the host: docker pull pglombardo/pwpush:2
- "manifest unknown" means the tag no longer exists.
- "toomanyrequests" is the Docker Hub rate limit. Log in with
docker loginto raise it. - "no space left on device" means a full disk. Reclaim space with
docker system prune
"exec format error"
This means the image was built for a different CPU architecture than your server.
- This image supports:
amd64 - Check yours with
uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.
Container keeps restarting
The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.
- Check the logs right after a restart, the last few lines before it died are the useful ones.
- Get the exit code with
docker inspect <container> --format '{{.State.ExitCode}}' - Still stuck? Redeploy once with the restart policy set to
noso the failure stays visible.
Required settings are blank
PWPUSH_SECRET_KEY_BASE has no default value, and password-pusher may crash or misbehave if left empty.
- Fill it in on the deploy screen before hitting deploy.
Stack won't deploy
Compose stacks fail fast on small mistakes, and Portainer shows the reason just above the editor.
- YAML only accepts spaces for indentation, a single tab breaks the whole file.

A Compose stack
Password Pusher is a Compose stack, a set of containers defined in one file and brought up together by Portainer, then started and stopped as a single app.
The app image
An image is the app packed up ready to go, everything Password Pusher needs bundled into one download. This template pulls pglombardo/pwpush:2, which Docker fetches once (about 198 MB) and then starts your own copy from.
Where the image comes from
Docker pulls its images from registries, public libraries of ready-built apps. Password Pusher's comes from Docker Hub, published by pglombardo.
Version tags
The bit after the colon in the image name is the version tag. This one pins 2, so every redeploy gives you that exact build until you bump it yourself.
Which machines it runs on
Every image is built for particular CPU types. This one ships for amd64, so it runs on regular x86 PCs and servers, though not ARM boards like a Raspberry Pi.
Volumes
A volume is where Password Pusher keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:
/opt/PasswordPusher/storagekept in thepwpush-storagevolume Docker manages
Environment variables
Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Password Pusher takes 7 of them, and 2 need a value before it'll start properly:
PWPUSH_MASTER_KEY, needs a value. Encrypts the text of every push. Exactly 64 hex characters, so generate it with: openssl rand -hex 32. Keep it the same when you redeploy, or older pushes can't be opened.SECRET_KEY_BASE, pulled from your own environmentPWP__ALLOW_ANONYMOUS, defaults totruePWP__DISABLE_SIGNUPS, defaults tofalsePWP__FILES__STORAGE, defaults tolocalPWPUSH_SECRET_KEY_BASE, needs a value. Keeps people logged in through a restart. Generate one with: openssl rand -hex 64. Leave it blank and every restart logs everyone out.PWPUSH_PORT, defaults to5150. Host port for the web UI
Restart policy
The restart policy here is unless-stopped, so Docker restarts Password Pusher after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).
Networking
Nothing custom is set, so Password Pusher sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.
Container name
Once it's deployed, Portainer names the container password-pusher. That's what you'll spot in the containers list and use in commands like docker logs password-pusher.
Platform
The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.
Open source license
Password Pusher is open source, released under the Apache-2.0 license. In plain terms the code is out in the open, so you're free to run it and change it to fit what you need.
Portainer app templates
Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set Password Pusher up. Add the template list to Portainer once, then deploying Password Pusher is a click rather than a wall of config.
