Problem building Docker

[CorMelse]

#Hi

I am trying to build a Docker image from the GHC code and am running into some errors I don't understand. Could be my knowledge level, but on advice of Justb4 I would like to ask this community what I am doing wrong, or is it a (known) bug?

I started out with a fresh installed Ubuntu 16.10, followed the installation instructions on the Docker site, created a directory in my home/Ontwikkel directory called "GeoHealthCheck" and installed Git.
Here is a snippet from my history file:

1964 sudo apt-get update
1965 sudo apt-get upgrade
1966 sudo apt-get install apt-transport-https ca-certificates
1967 sudo apt-key adv
--keyserver hkp://ha.pool.sks-keyservers.net:80
--recv-keys 58118E89F3A912897C070ADBF76221572C52609D
1968 echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" | sudo tee /etc/apt/sources.list.d/docker.list
1969 sudo apt-get update
1970 sudo apt-cache policy docker-engine
1971 uname -r
1972 sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual
1973 sudo apt-get update
1974 sudo apt-get install docker-engine
1975 sudo service docker start
1976 sudo docker run hello-world

1979 cd Ontwikkel/
1980 ll
1981 mkdir GeoHealthCheck
1982 cd
1983 sudo apt install git
1984 git config --global user.email "cor.melse@rivm.nl"
1985 git config --global user.name "Cor Melse"
1986 cd -
1987 git init
1988 git clone https://github.com/geopython/GeoHealthCheck.git
1989 cd GeoHealthCheck/docker/
1990 ll
1991 sudo docker build -t yjacolin/geohealthcheck .

When I tried to build the Docker image with the last command, as described in the read-me the following error appears:

unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/melsec/Ontwikkel/GeoHealthCheck/docker/Dockerfile: no such file or directory

the Dockerfile is present within the subdir docker/GeoHealthCheck but this won't work for me mow.
What's my mistake, or what's the bug here?

Thanx for the effort,
Cor

cc @justb4 / @yjacolin - any suggestions?

[justb4]

@CorMelse you have to build one directory deeper, i.e. i.s.o. 1989 cd GeoHealthCheck/docker/ do
cd GeoHealthCheck/docker/GeoHealthCheck where Dockerfile resides, and then sudo docker build -t yjacolin/geohealthcheck. We should update README for that as well.

[yjacolin]

Please could you send a PR to add "cd docker" in the build section of the README? @justb4 is right

[CorMelse]

Indeed, this solves my problem!
When editing the README maybe point out that one must "sudo" the commands?

Thanx anyway @justb4 @yjacolin

[yjacolin]

the sudo command is not mandatory, it depends if you added yourself in the docker groups (which I did).

[justb4]

Ok, I updated the README, interpreted that @yjacolin replied to my comment above...so @CorMelse : no PR required for now. More info possibly best added to GHC RTD docs, like how to use the Docker-compose stuff...
