docker issue during hab export

[mostafahussein]

I am following the tutorial steps and currently i am on this step:

[default:/src:0]# hab pkg export docker myorigin/mytutorialapp

and i am getting the following error

★ Install of core/hab-sup complete with 12 packages installed.

• how should i solve it ?

[mostafahussein]

I am updating docker on the host, will update and close the issue if this will solve it for me

FWIW, I had the same issue in the past and upgrading Docker worked for me.

Now i am getting another issue:

Cannot connect to the Docker daemon. Is the docker daemon running on this host?

However docker service is running on the host, i am using fedora

I think its about the docker api, i guess i faced this issue once before and it was something to do with the docker init script, but i cannot remember what i have done before

[davidwrede]

I've seen comments for this on SO to add yourself to the docker group, stop/start the Docker service, etc.

The tutorial has you export to Docker to show how easy it is to export a Habitat package into another runtime format, but if you're running on Linux, you can start the Habitat service directly. Check out the instructions on Run packages on how to do that.

[mostafahussein]

for the usermod part i already made it. but do you think that runing habitat as a service will fix this issue ?

[davidwrede]

Running natively won't fix the Docker issue, but it will show you how a Habitat service starts up and runs.

[mostafahussein]

I cant figure out how habitat interacting with docker.
for example i have tried the following and i can use the API without problems. but in case of habitat i don't know if it tries to connect to a specific port or it try to connect through another way. do you have any information ?

[mostafahussein]

solved by adding the root to docker grp. i didn't notice that habitat was using the root not my user. thanks david
