sparklyballs Posted April 11, 2015 Share Posted April 11, 2015 It looks like the current version of phusion/baseimage is 0.9.16. According to the release notes, it disables ssh. Is there a reason the recommended version is 0.9.15 instead? According to the release notes: 0.9.16 (release date: 2015-01-20) docker exec is now the default and recommended mechanism for running commands in the container. SSH is now disabled by default, but is still supported for those cases where "docker exec" is not appropriate. Closes GH-168. All syslog output is now forwarded to docker logs. Closes GH-123. The workaround for Docker bug 2267 (the inability to modify /etc/hosts) has been removed, because it has been fixed upstream. Closes GH-155. Logrotate now reloads syslog-ng properly. Closes GH-167. Fixed some locale issues. Closes GH-178. Thanks to David J. M. Karlsen. Fixed problems with cron. Closes GH-115. Contribution by Bryan Bishop. may be as simple as a lack of maintenance on that thread, OP is on something of a sabbitical. I do hope the OP comes back to the fold though, a good source of information and an invaluable help in many things, sorely missed. Quote Link to comment
BRiT Posted April 11, 2015 Share Posted April 11, 2015 Ahh, I looked at a couple of example dockfiles and they were pointing to 0.9.15, which is what is recommended on one of the follow-up pages of this thread. Looks like you've already updated, so nevermind! there were some encouraging noises not so long ago about an unraid base image which i liked the look of. although the runit system in phusion works for the vast majority of containers, i've found some instances where it is too sensitive and respawns apps that haven't crashed, i'm leaning more and more towards supervisor. I've only seen that happen if the process it runs spawns itself into the background and returns to the caller; for instance the program you're running is loaded as a daemon itself.

binhex Posted April 12, 2015 Share Posted April 12, 2015 I like supervisor a lot and use it for all my docker images, however I must make you aware it lacks one important feature and that's dependency management. There is a long standing request for this, hoping it gets included soon. Quote Link to comment
brettm357 Posted March 24, 2017 Share Posted March 24, 2017 So having a go at creating dockers - Is phusion base image still the preferred image use Quote Link to comment
saarg Posted March 24, 2017 Share Posted March 24, 2017 I would use alpine, debian or Ubuntu depending on which software you try to run and then use the S6 overlay process monitoring and init of software. 1 Quote Link to comment

Maniac Posted August 25, 2017 Share Posted August 25, 2017 What do we need to do with our custom Docker images on unraid in order to get the "Edit Docker" option in the webui? I can see that the dockers I have installed via Community Apps all have that, and you can set different options like port and cpupins ect. So how to add same feature to our own dockers? Thanks Quote Link to comment
Squid Posted August 25, 2017 Share Posted August 25, 2017 You have to add them via the add template and fill out the info. Adding via a manual command will not give the editSent from my LG-D852 using Tapatalk Quote Link to comment

For example these types of app specific options: Quote Link to comment
Squid Posted September 1, 2018 Share Posted September 1, 2018 (edited) As best it can. It's not like it can read the directions or anything. If the container author included the various environment variables, paths, etc within the dockerfile, then it should properly fill out the template (minus any help text like what you posted above), and certain assumptions are made about network type, webUI port etc which is impossible to determine, and may or may not be correct. But, there is zero requirement that the dockerfile contains that information within it, and no matter what you still have to read the docs on the dockerhub page for the container - Hence why its an option in CA that the user has to specifically enable and then have another click in order to display the results from dockerHub Edited September 1, 2018 by Squid 1 Quote Link to comment

Not sure what is involved in actually getting your app added to Community Applications, Squid is in charge of that. 1 Quote Link to comment

I am attempting to pull a linux application into unraid as a docker. My Dockerfile seems to work at my linux commandline when launched as a daemon but when I pull it into unraid via the "add container" option it doesn't run. Doesn't really do anything, nothing in the log. I suspect I am missing the process monitoring and init mentioned above. Be gentle, I am new to this process. Would anyone mind giving me a pointer as to what I am missing? I have been tring to follow examples from linuxserver.io, binhex, and ich777. Most are not issuing the CMD at the end of the Dockerfile to kick off a process. I added one to mine which makes it work from my linux dev box command line but when deployed in unraid, no worky.

Squid Posted April 19, 2020 Share Posted April 19, 2020 As a start, I would think you should look at the difference between whatever docker run command you're issuing manually, and what the docker run command is when you enter the applicable info into a template. Quote Link to comment
kiowa2005 Posted April 19, 2020 Share Posted April 19, 2020 (edited) @Squid, Thanks for responding. I believe I am doing the same thing at the command line that unraid would be attempting to do when I click start: docker create --name='derbynet_server' --net='somenet' -e TZ="America/Chicago" -e HOST_OS="Unraid" -e 'TIMER_USERNAME'='Timer' -e 'TIMER_PASSWORD'='xxx' -e 'PUID'='99' -e 'PGID'='100' -p '8070:80/tcp' -p '8071:443/tcp' -v '/mnt/cache/appdata/derbynet_server/config':'/config':'rw' 'mitchellriley/derbynet_server' It is running fine from the linux command line. In unraid, it doesn't start at all, no errors. just a blank log. Edited April 19, 2020 by kiowa2005 Quote Link to comment
Squid Posted April 19, 2020 Share Posted April 19, 2020 That's not the command that the template returns though. Unless I misread it, you wanted to know why it works at the command prompt and not via the template screen. Quote Link to comment

Unless I misread it, you wanted to know why it works at the command prompt and not via the template screen. I was using the command from the template. I paraphrased a bit since I was usign it on a different machine. I shortened the path and edited the -net parameter but the same command none the less. I deleted the docker and re-installed it. Now it starts and stays running so I am not sure what changed but I will take it. However, when I click the log next to it I don't see any output. Do I need to do something special in the Dockerfile to ensure the syslog or some other output is feeding that log view? Thanks Quote Link to comment
kiowa2005 Posted April 19, 2020 Share Posted April 19, 2020 Still having issues: This docker seems to need both an "nginx" and "php-fpm7.2" process running. I attempted the following: CMD service php7.0-fpm start && nginx -g "daemon off;" However, it seemed to not understand how to start as a service and wanted an absolute path. This has lead me down the path of supervisord to launch both processes. https://stackoverflow.com/questions/37313780/how-can-i-start-php-fpm-in-a-docker-container-by-default/37313908 I would think that the combination of FPM and nginx has been done before. Am I going down a rabbit's hole or is this the best approach? Quote Link to comment
