docker configuration [SOLVED]

Paul15071992 · 2014-11-27 13:29:00

Hello,

I'm trying to configure a docker, but I don't really know how to do it. First I read the documentation from the wiki, but it wasn't enough. I did the same configuration on Ubuntu, but there, the docker config file is different.

I want to configure the docker like this (Ubuntu configuration):

DOCKER_OPTS="--bip=172.17.42.1/16 --dns=172.17.42.1 -H tcp://192.168.1.1:4243 -H unix:///var/run/docker.sock"

Could somebody give me a hint?

Thank you!

You need to setup a systemd override file with the correct options. I'm on mobile right so I can't easily give an example... Hopefully that sends you in the right direction for now.

Edit (at my computer now):

Create file /etc/systemd/system/docker.d/my_config.conf

[Service]
ExecStart=
ExecStart=/usr/bin/docker --bip=172.17.42.1/16 --dns=172.17.42.1 -H tcp://192.168.1.1:4243 -H unix:///var/run/docker.sock

From 'man systemd.unit':

Along with a unit file foo.service, a directory foo.service.d/ may exist. All
files with the suffix ".conf" from this directory will be parsed after the file
itself is parsed. This is useful to alter or add configuration settings to a
unit, without having to modify their unit files. Make sure that the file that
is included has the appropriate section headers before any directive. Note that
for instanced units this logic will first look for the instance ".d/"
subdirectory and read its ".conf" files, followed by the template ".d/"
subdirectory and reads its ".conf" files.

You have to put the blank ExecStart= line in to ensure that directive gets overridden.

I did that and then restarted the docker, but after the restart, when using the command

systemctl status docker

I get the a failure

Two things:

1. Provide the relevant journactl output for docker.service
2. Try starting docker from the command line directly with those options to make sure you got the options right

The drop-in configuration dir should be "docker.service.d". When systemd sees it, any *.conf files should also show up in systemctl status output.

Paul15071992 · 2014-12-01 09:07:37

there is no file

docker.service.d

all I have are

/usr/lib/systemd/system/docker.service
/usr/lib/systemd/system/docker.socket

Well, it says you've got -H listed twice. It looks like you do...did you try taking out one of the -H parameters?

Oops, sorry didn't notice before... you're missing the -d flag (run as daemon) from the docker command line.

Scott

Paul15071992 · 2014-12-04 08:00:58

if I run sudo docker -d, I get

2014/12/04 08:58:56 docker daemon: 1.3.2 39fa2fa; execdriver: native; graphdriver: 
[0179cb16] +job serveapi(unix:///var/run/docker.sock)

[info] Loading containers: 
.....................................................................[info] : done.
[0179cb16] +job acceptconnections()
[0179cb16] -job acceptconnections() = OK (0)

so I think that it works now.

thank you!

i managed to solve the problem, by exporting my options in DOCKER_HOST and DOCKE_OPTS

When you get it working right, make to post your final solution for posterity and mark your thread as [SOLVED]

Paul15071992 · 2014-12-10 10:40:11

My solution:

/etc/systemd/system/docker.service.d/my_config.conf

[Unit]
Description=Docker Application Container Engine
Documentation=http://docs.docker.com
After=network.target docker.socket
Requires=docker.socket

[Service]
ExecStart=
ExecStart=/usr/bin/docker -d --bip=172.17.42.1/16 --dns=172.17.42.1 -H tcp://127.0.0.1:4243 
LimitNOFILE=1048576
LimitNPROC=1048576

[Install]
WantedBy=multi-user.target
Also=docker.socket

.bashrc

export DOCKER_HOST="tcp://127.0.0.1:4243"

because the docker is listening to the address "127.0.0.1:4243"
