Docker-images: Exposed Ports Are Not Accessible For Oracle 18c XE

[arnab-das]

I've the following configuration

Ubuntu 18.04
Docker 19.03.6

Built the docker image for Oracle 18c XE following the instructions and ran the image with the following command

docker run -d --name oracle18cxe -p 28080:8080 -p 25500:5500 -p 21521:1521 -e ORACLE_PWD=sAdnew123 oracle/database:18.4.0-xe

Now, whenever I do curl -k https://localhost:25500/em on the host, I get Connection reset by peer. What am I doing wrong?

Tried to rerun that and get a similar issue:

[oracle@ol7 ~]$ curl -k https://localhost:25500/em
curl: (35) Encountered end of file

I could work around by resetting the port:

[oracle@ol7 ~]$ docker exec -ti oracle18cxe su -p oracle -c "sqlplus / as sysdba"

Can you try that?

Hi again! Faced exactly the same issue. Tried @gvenzl solution and it worked for me (except I checked it right from my host machine and browser opened EM page).

Hi! Same issue by me on Windows 10 with the newest Docker Desktop Community 2.2.0.4 (43472). Workaround from @gvenzl works.

Closing this issue as a workaround is available and the issue is related to OEM Express in XE, rather than the Docker build files.
