Lava Dockerfile Fatal Error: host.json not found. Copy host.json.example to host.json

[Kigorky]

Hi,

I have been trying to use lava but i am unable to do it:

First cloning the repo i run the setup.py and i got the following dependencies errors:

[setup.py] Installing LAVA apt-get dependencies

[setup.py] Running [sudo apt-get -y install libjsoncpp-dev postgresql jq python-psycopg2 python-sqlalchemy socat libpq-dev cmake docker.io bc python-pexpect python-psutil python-lockfile genisoimage inotify-tools build-essential python-pip libprotobuf-c0-dev libodb-pgsql-2.4 libfdt-dev] . . .

Package python-pip is not available, but is referred to by another package.

However the following packages replace it:

Furthermore i tried to use the dockerfile to build the docker image, ran the configure script in the /libodb-pgsql-2.4.0 directory and cloned the lava repo whitin the docker container. When i run the following command:
$ ./scripts/lava.sh toy
i got:
[everything] Parsing args [everything] All steps will be executed Fatal error: host.json not found. Copy host.json.example to host.json

So can you help me please ?

Thank you.

I'm not sure about the first one (my guess is that you are trying this on a newer version of Ubuntu, and some older versions of Python have been removed), but for the second issue, did you try doing what the error message says?

[everything] Parsing args [everything] All steps will be executed Fatal error: host.json not found. Copy host.json.example to host.json

In other words, try copying host.json.example to host.json ?

The host.json.example file is within the lava directory and that is ok, but where the host.json file is ? By searching for it using the command $ find / -type f -name "host.json", there is no output. So it seems that is not in the docker container.

Right - the error message is telling you that you need to copy host.json.example to host.json. As in:

cp host.json.example host.json

cp host.json.example host.json

i had done it however i got the following output:
[everything] Parsing args
[everything] All steps will be executed
Fatal error: /home/fasano/lava/target_configs/toy/toy.json not found. Did you provide the right project name?

I think the script is searching for the toy.json file in the wrong path. By cloning the repo from github the right path of the toy.json file is:
/lava/target_configs/toy

but it is searching for it in /home/fasano/lava/target_configs/toy/toy.json

I edited the scripts and now everything seems to be ok ;) thank you

Glad to hear it! I'll close this issue.
