Are you running within a zero-trust environment like ZScaler ?
Feels like your issue is not ClearML itself, but issue with https/SSL and certificate from your zero-trust system

This is the last situation
I could create a docker that works

FROM pytorch/pytorch:2.2.1-cuda12.1-cudnn8-runtime

WORKDIR /app

# Install system dependencies
RUN apt-get update && apt-get install -y \
    libgl1-mesa-glx \
    libglib2.0-0 \
    git \
    curl\
    && rm -rf /var/lib/apt/lists/*

# Install dependencies
COPY requirements.txt /tmp/requirements.txt
RUN pip install --no-cache-dir -r /tmp/requirements.txt

# Update CA certificates
COPY hme_root_CA.crt /usr/local/share/ca-certificates/hme_root_CA.crt
RUN update-ca-certificates

ENV SSL_CERT_FILE=/usr/local/share/ca-certificates/hme_root_CA.crt
ENV REQUESTS_CA_BUNDLE=/usr/local/share/ca-certificates/hme_root_CA.crt
ENV PIP_CONFIG_FILE=/root/conda.conf
ENV CLEARML_AGENT_SKIP_PYTHON_ENV_INSTALL=true
ENV CLEARML_AGENT_SKIP_PIP_VENV_INSTALL=true

RUN pip config set global.cert /usr/local/share/ca-certificates/hme_root_CA.crt
RUN pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
RUN conda config --set ssl_verify /usr/local/share/ca-certificates/hme_root_CA.crt

COPY conda.conf /root/conda.conf


# Configure ClearML
COPY clearml.conf /root/clearml.conf
RUN clearml-init

# Start ClearML worker
CMD [ "clearml-agent", "daemon", "--queue", "default", "--foreground" ]

But it just works if I use clearml-agent daemon --gpus 0 --queue default --foreground

If I try to use clearml-agent daemon --gpus 0 --queue default --foreground --docker (in the host)
When It opens the docker mentioned above, it always tries to install different apt packages, and tries to install some conda packages and gets stall

Do you know if is possible to avoid all the installations? And just run everything in the docker's environment?

You are using CLEARML_AGENT_SKIP_PYTHON_ENV_INSTALL the wrong way

CLEARML_AGENT_SKIP_PIP_VENV_INSTALL need to be a path

while the other may need to be 1 instead of true

eg: None

I changhed that
But it continues trying to install the next packages:

(this installation has some errors or warnings in the middle)
Then it tries to install with pip, but it gets stall after it finish and doesn't continue any more

It could be something related with conda in the docker?

Hi @<1576381444509405184:profile|ManiacalLizard2> at the end we make it works
It has a lot of warning but is able to run the experiments hahaha
Thanks for your help

so what was the solution/hack then ?
