# Set up internal package hosting

Many customers maintain internal mirrors of public package repos. This is typically done while they use a whitelist to remove access to external, public repositories. This might be for security or for standardization.

You can add the following to the Dockerfile instructions in your global [Compute Environments](/cloud/platform-capabilities/core-concepts/compute-environments/manage-compute-environments) to set Conda, pip, or RStudio to reference your internal mirrors by default:

```dockerfile theme={null}
RUN
   # Add $CUSTOMER mirrors to condarc config files. Also disabled auto_update since mirrors are not always up to date.
   printf "
channels:
  - $CUSTOMER_CHANNEL_1
  - $CUSTOMER_CHANNEL_1

" >> /opt/conda/.condarc &&
   printf "
allow_other_channels: False
" >> /opt/conda/.condarc &&
   printf "
ssl_verify: False
" >> /opt/conda/.condarc &&
   printf "
show_channel_urls: True
" >> /opt/conda/.condarc &&
   printf "
auto_update_conda: False
" >> /opt/conda/.condarc &&

   # Pointing R to $CUSTOMER CRAN mirror
   printf "
local({
  r <- getOption('repos')
  r['CRAN'] <- '$CRAN_MIRROR_URL'
 options(repos = r)
})
" >> /home/ubuntu/.Rprofile &&

   # Pointing pip to $CUSTOMER PyPi mirror
   printf "[global]
index-url=$CUSTOMER_PYPI_MIRROR
trusted-host=$IP_OR_FQDN" > /etc/pip.conf &&

   chown -R ubuntu:ubuntu /home/ubuntu /opt/conda/
```
