I tried these 4 obscure Docker containers, and now I run them 24/7


Docker is one of my favorite things about Linux. I like Docker because it’s based around open-source containers, efficient for my needs, and most containers are, in my experience, simple to work with.

I like to test and experiment with different ones to help with my productivity, RSS feeds, and data management.

With that in mind, I found six obscure and lesser-known Docker containers that I now use all day, every day.

You Should Learn Docker Before Buying a NAS (Here’s How)

Docker can turn your NAS into your own cloud that can host your own apps and automate your home.

Papermerge

A neat document manager that has OCR

Papermerge is a document management tool. I can be very chaotic and disorganized at times, so it helps to have some kind of management system to keep things in order. I made a YAML file using the most basic setup (except I used port 8000), and ran it using Docker Compose using Docker Compose Up. This is the same process for all the Docker Compose apps on this list.

Papermerge is a useful document manager. It’s open-source and password-protected, with built-in OCR features. I have far too many documents just lying around on my various drives. It’s not super organized, so I figured I could use a digital file cabinet.

Papermerge is exactly that. I scan receipts, bills, notices, tax documents, manuals, old advertisements from the back of comic books, and handwritten notes into it. And it does a fine job of decoding my chicken scratch handwriting.

Actual Budget

A local budgeting tool eliminated the need for spreadsheets

There was a time when I swore by spreadsheets. I used them for everything and even liked to get creative with my designs. Then I learned about Actual Budget and found it to be a much better budgeting/accounting tool than any spreadsheet I’ve ever made. I copied the YAML file from the Actual Budget repository into nano, configured the container to port 5006, and got started in a few seconds.

I immediately liked the layout and simple interface. I started building a budget, first in the Budget tab. I put in a budget of $300 for this experiment, but when I use it in the future, I’ll adjust that. I created a list of payees and began to input due dates and amounts. Within a few minutes, I had an entire sketch of what my budget for the upcoming week looks like. With everything represented visually, it’s easier to see if there are gaps or areas where I can cut.

Some of the other features are useful as well, including the Reports tab, which shows me where I’ve gone horribly wrong in my financial life. I use Actual Budget every day to check on the status of my budget, and I configured the container to immediately add my funds to the budget on pre-determined paydays. It’s lightweight, focused on privacy, and doesn’t have any subscription fees, making it one of my favorite daily-use Docker containers.

Wallabag

A fantastic replacement for apps like Pocket

I miss Pocket. Instapaper just doesn’t do it for me nowadays, and RSS feeds only get you so far. Wallabag has become another tool in my self-hosting arsenal. I set this one up on port 8082 and made some adjustments to the basic YAML file to suit my tastes. To add a link, you simply click the plus sign at the top of the app and paste the link into the box.

In a few seconds, the story becomes a part of your library. I tested Wallabag with some of my published work. It did quite well with most of it, although it had some trouble saving one of the listicles I wrote a few years ago. I added a few other links from various publishers and was pleased to see they were saved properly.

Reading on Wallabag parallels the experience of using Pocket in the olden days. I find myself using this one more frequently than any of the other containers I’ve found. There’s also a Chrome and Firefox extension. You can generate an API token within the app, then use it and your credentials in the extension to enable saving from anywhere you browse. It’s a handy feature that puts this container on par with what Pocket used to be.

Reading in the app is straightforward and likely what you’d expect from an article-saving app. It won’t always capture the full text (I saved one of my old Ranker listicles, for example, and it unsurprisingly only captured the first page), so it’s not foolproof. Regardless, I tend to save a ton of articles for later reading, so Wallabag has definitely come in handy as of late.

Excalidraw

A browser-based whiteboard tool

Here’s a truly unique container: a browser-based whiteboard. Excalidraw is useful for my notes, collaboration, and some of my more complex projects. I’m using it to design a Choose Your Own Adventure web page for a songwriting project I’m working on. Heavy vector tools or paint programs can take a long time to configure or set up, but Excalidraw loads in a few seconds.

When I want to use something with strong visuals or just make something in my head, I’ve found Excalidraw ideal. In addition to my creative projects, I have been using it daily for outlining articles and sketching out various ideas. It keeps me grounded in something simple without worrying about making something pixel-perfect, changing out my art supplies, or getting hand cramps.

Although my adventures with Docker began with setting up Fresh RSS, I’ve found so many other useful tools that exist beyond the mainstream.

Docker is an efficient way to try out new tools, and I’m looking forward to finding (and testing) more obscure and lesser-known/obscure containers for my next home lab experiment.

Tommiee lost both parents when he was young and grew up in the care system, moving between different families and situations. These early experiences followed him into adulthood – he often felt like he didn’t belong, and ongoing housing challenges meant he never had a true sense of security. Despite everything, he held onto hope, and he found community in places where he felt understood, like the skate park in Bedminster.

In this interview with senior support worker, Fisayo, Tommiee reflects on his journey and how meeting Second Step helped him finally find stability after a lifetime of instability.

Dean Lane skate park, near North Street in Bedminster, has been a cornerstone of Bristol’s skate community for decades. Since opening in 1978, it has served generations of skaters and become a much‑loved fixture of the neighbourhood.

“Sharing a space like this, you know, I feel like for a lot of people that don’t want to be at home, or have difficulties inside or with themselves, or interacting with people, it’s a place where you can come,” says Tommiee, “It’s like an outdoor mental health men’s club. So having the opportunity to come back here, even though I don’t live here anymore now, is good, you know?”

Although he doesn’t live in Bedminster anymore, Tommiee came back to the skate park to meet his support worker, Fisayo, and tell his story:

Tommiee: “My name is Tom – Tommiee Mosarey – also known as BS3 Chase. I came to Second Step because I was probably going through a hard time in my life and I was having difficulty in my housing.”

Fisayo: “How has Second Step helped you? How’s your journey been so far?”

Tommiee: “They moved quickly. They actually listened to me, so I’m happy to be where I am now.”

Fisayo: “Do you want to tell a bit about your background and what you faced growing up till now?”

Tommiee: “Yeah, man. I faced a lot. I think everyone’s got a story to tell that would make you feel sad. But, obviously having to deal with that every day… My parents died when I was a baby. I was very young and obviously due to that I had to grow up in different situations, in different families, and yeah it was kind of hard.

“I was always me, if you know what I mean. I had to find me and then find out how I fit into society, you know.”

Fisayo: “What would you say is one thing that actually kept you going?”

Tommiee: “I guess my energy, my resilience, me wanting to have a happy ending, me knowing that it’s working out for this person over here, it’s working out for those people over there. I’m going to get my time soon, and it’s just waiting for the stars to align. Just waiting and being patient.

“I was actually going to give up before Second Step came, not give up but… let me explain this: before Second Step, it was like another house, another home, another group of people that I had to go and see and work with who were going to promise me my happy ending. And I had been failed up until then. And then obviously I met you guys. So I was a bit hesitant at first, and then obviously I met you and we sat down, we spoke, and we had similar interests. So I think that’s what made me grow to you and then, I don’t know, I just was like I trust you, you know? And then, I’m still here now, so it works out.”

Fisayo: “Do you find using a support worker helpful in any way?”

Tommiee: “I think Second Step try and pair you with somebody that you will actually resonate with. I learned how to open up and trust you about other things that I couldn’t do or I didn’t know I had to do that were the steps to take to get my own independence.

“So now I am, and my life’s changed. I got a new job, I live in a whole new area. It’s a lot of responsibilities but living in Second Step (Toll House Court) and taking that step initially and working with you, realising that good things can happen to all of us.

“Like I said at the beginning, everyone’s probably got a story to get you that’s probably going to make you feel sad, do you know what I mean? But it’s part of our movie. And even if you have no one and feel like you got no one, there’s always someone there. There’s always a service there. There’s always a person like you to help, that genuinely just wants to help another person. And when you’re human about it, it’s great and it works out.

“I’ve been through a lot of services, a lot of different things, you know, just growing up from a kid in the system, like a little baby into an adult. I feel like every single one of them services kind of let me down. But every single one of them was a step to find the right step for me, which was Second Step.

“And I feel like, especially the last seven years before I met you guys, being here in Bedminster and growing up and finding myself, it’s great on the outside, but my home life wasn’t great. I was living in shared houses with other people who had issues and problems and stuff like that. And if you do get the opportunity to get engaged with services like Second Step – really lucky. The person they’ve got to work with you, they’ll match you with someone that you know you’re comfortable with. They can see where you’re going wrong and then kind of point you in the right direction, you see what I’m saying? I feel like that’s what you’ve done for me really. I just hope that you’re proud of me, you know?

Fisayo: “Definitely. I’m proud of you. You made the right choice, you know, taking the right steps and we can only wish you the best. And just keep your head held high, keep it moving. So many dreams out there and so many things to achieve as well. Proud of you, man. Yeah, man, that’s good. Thank you.”

Thank you to Tommiee for sharing your story of hope and courage, and to Fisayo for the support and compassion that helped Tommiee along the way.
