/bin/sh: pecl: not found

[yunus89]

Using this Dockerfile, i added another needed package by my application called opencensus-alpha. The package is installed using pecl.

So by adding the following line of code in the already existing Dockerfile
RUN pecl install opencensus-alpha
an error was thrown

Step 4/18 : RUN pecl install opencensus-alpha
 ---> Running in 4d0f464fb79c
/bin/sh: pecl: not found
The command '/bin/sh -c pecl install opencensus-alpha' returned a non-zero code: 127

How can i install pecl or packages installed through it with this Dockerfile

Hi @yunus89 ,

Pecl is part of the php7-pear package. You can instal this package with

RUN apk add --no-cache php7-pear

Then you should be able to run pecl.

For opencensus-alpha to be installed via pecl following are needed

RUN apk add --no-cache php7-dev php7-pear
RUN apk add autoconf gcc g++ make
RUN pecl install opencensus-alpha
