Dockerfile for Umbraco 13
# help-with-umbraco
s
Does anyone have a good working example of a Dockerfile for Umbraco 13. I'm having all kinds of issues with permissions and the site not booting. Anything I've searched has been older versions. Also, I'm targeting Linux.
c
Copy code
USER root
RUN chmod o=rw /app/wwwroot/
RUN chmod o=rw /app/Views/
had to change the permissions on those two directories
This got us running in linux containers (running in Azure Container Apps)
a
My dockerfile is nothing else then the basic VisualStudio generated one
Copy code
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
WORKDIR /src
COPY ["ProjectName/ProjectName.csproj", "ProjectName/"]
COPY ["ProjectName.Business/ProjectName.Business.csproj", "ProjectName.Business/"]
COPY ["ProjectName.Data/ProjectName.Data.csproj", "ProjectName.Data/"]
RUN dotnet restore "ProjectName/ProjectName.csproj"
COPY . .
WORKDIR "/src/ProjectName"
RUN dotnet build "ProjectName.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "ProjectName.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ProjectName.dll"]

@Ambert That's not on .NET8 though.. which changed the permission model for containers to no longer run as root
a
Hmm, I havent tested that yet, correct
curious if ill encounter the same issue
Have just made the upgrade locally to v13, so could check it today/tomorrow if it runs on my azure container

https://github.com/liamlaverty/ideal-umbrella/blob/main/IU.Docker/dockerfile.umbracosite https://github.com/liamlaverty/ideal-umbrella/blob/main/docker-compose.yml This repo has a working dockerfile for Umbraco13. The 
docker-compose.yml
file launches both a backoffice & front-end Umb site from that 
dockerfile.umbracosite

Yea same issue here, site wont come up
Copy code
unhandled exception. System.UnauthorizedAccessException: Access to the path '/app/umbraco/Data' is denied.
Definitly permission issue, uf
i
you might need to delete the umbraco folder if its in a named volume. If it creates it itself the problem is solved
You do need this though @Ambert

Will check in a min, thanks, missed your message

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 8080
EXPOSE 8081
EXPOSE 443

What worked for me is adding the chmods (Didnt need to add the user root), and also the Expose ports as in .net 8 the port is default 8080. In my Appservice I added an environment variabele called WEBSITES_PORT with 8080 and all is working for now, not sure if this is the best approach though 🙂

Ahhh! So I was trying to set permissions in the final stage and it was giving me a hard time. Thanks everyone! Really appreciate the help!
