missing ts-node-dev

[jbhardman]

When running docker-compose up, the containers for todo and auth fail to start because of the missing command ts-node-dev.

opentelemetry-101-todo-1   | yarn run v1.22.15
opentelemetry-101-auth-1   | yarn run v1.22.15
opentelemetry-101-todo-1   | $ ts-node-dev todo-service.ts
opentelemetry-101-auth-1   | $ ts-node-dev auth-service.ts
opentelemetry-101-todo-1   | /bin/sh: 1: ts-node-dev: not found
opentelemetry-101-auth-1   | /bin/sh: 1: ts-node-dev: not found

I tried tags 1 and 12. Same issue.

Can you try running yarn install?

[jbhardman]

Run it where? Inside the docker container? This build is all happening inside docker containers, not my local host.

[habmic]

Run it in the host, this is because there is a volume mounted for the host to the container

Hi need help, want to implement optel for mongodb in python, any suggestions or link how to use the same. I am new to opentelemetry and purchased ur course from UDEMY. Trying to make sense of the concept but I have PoC to complete, any suggestion documentation will help for metrics implementation

Run it in the host, this is because there is a volume mounted for the host to the container

It works after installation on HOST 👍

@habmic Can you please explain in more detail what this issue means? ran into same problem

[abhijeetNmishra]

got it resolved by adding the following code to docker-compose.yml file `volumes:

• .:/usr/src/app:rw
• /usr/src/app/node_modules`

Yes executing yarn install followed by docker-compose up solved the issue.

$ yarn install

Thanks for the advice. This really should be mentioned in the course video:) Having said that, the docker files in the course are using node 16, which is now somewhat old and unlikely to be the version on your machine. "yarn install" or whatever probably needs to be run from within a docker container on the same base image.
